Nom de Mom

Go To

Many years ago, Alice Troper married Bob Laconic and changed her last name to his. Their daughter Carol, however, opts to take Alice's last name instead of Bob's.

Reasons for Carol's use of her mother's maiden name vary. Maybe she had a huge falling out with her dad, maybe she's challenging traditional gender norms, maybe she doesn't want the burden of fame or infamy of her father's last name, maybe there's another Carol Laconic whom she doesn't want to be confused with or maybe she just doesn't like Bob's last name. In-story this can be used to hide the relationship between two characters until it's time for The Reveal, as a subtrope of Real Name as an Alias.


As a general rule of thumb, this trope should apply to children who originally went by their father's last name and made the change later, whether self-motivated or otherwise.

This trope does not apply to illegitimate children who use their mother's name because they can't go by their father's — the use of the mother's name should be a choice, not a necessity. Not to be confused with Unnamed Parent, where someone is treated as if her name is "Mom" because the story never gives any other name by which to call her.

    Anime and Manga 
  • In Ai Yori Aoshi, Kaoru Hanabishi retakes his mother's last name, Honjou, as he marries Aoi and they properly start a life together.
  • Ao Haru Ride: Kou changed his surname from Tanaka to Mabuchi because he grew up with his mother after his parents' divorce. His brother, Yoichi, was raised by their father, so he goes by Yoichi Tanaka. It's also noted that Kou is still grieving over his mother's death and not on good terms with Yoichi. Futaba's obsession over this is a minor plot point since Kou going by a different surname signals how he is a different person from the one she knew during childhood. Near the end of the series, after Kou moves on from his mother's death and starts dating Futaba, he reverts his surname back to Tanaka.
  • In Black Clover, Finral became the Black Sheep of the noble Vaude family due to being less gifted than his younger half-brother, Langris. When his father and Wicked Stepmother finally disowned him to make Langris the heir, Finral took his dead mother's surname, Roulacase.
  • Butterflies, Flowers: Choko's family sold their Big Fancy House to pay for their former servants' retirement. Domoto was so disgusted by his parents' refusal to do anything in return after prospering he took his mother's maiden name.
  • Masumi Sera from Case Closed uses her mother's surname, Sera, instead of using her father's, Akai. This is likely to hide the fact that she is Shuichi Akai's younger sister.
  • Code Geass:
    • Kallen goes by her Japanese mom's name, Kozuki, when she's working with the Rebellion rather than her Britannian father's name, Stadfeldt. This serves the dual purpose of disguising her identity and showing that she identifies more with her mom's side of the family, as well as a form of rebellion since being a Britannian carries many more rights than being an "Eleven" or Japanese person.
      • Considering Kallen spent most of her life in her mother's care and her brother's name is also Kozuki, it could be that Kozuki is in fact her birth name, and Stadtfeld was the name she took later to become her father's heir.
    • In the audio drama Stage 0.916, where Lelouch first meets Rivalz Cardemonde, it is said that Rivalz goes by his mother's maiden name because he does not get along with his father.
    • A careful eye makes it clear this is common for the Britannia Royal family; despite the Emperor being of the zi Britannia family, all of his many, many children use the "whatever" Britannia name that their mothers have; such as vi Britannia, la Britannia, li Britannia, and more. Why this is so is never explained but since it's never remarked upon it most certainly is considered "normal".
      • A possible explanation is that the nobility articles are to identify which prince or princess belongs to which empress consort; since the emperor can have multiple wives, it would be confusing for the average person to keep the imperial genealogy straight, so by each empress and her children using the same particle, it cuts down on the confusion.
  • In Dear Brother, Mariko Shinobu takes up her mother's maiden name, Shikiya, after her parents' scandalous divorce.
  • Similar to Yu-Gi-Oh example, Takeru Takaishi of Digimon Adventure bears his mother Natsuko's surname since his parents divorced, while his older brother Yamato retained their father's surname Ishida.
    • Sora Takenouchi also goes by her mother's surname for a different reason — Toshiko Takenouchi is the Grand Master of a prestigious school of Japanese flower arrangement (ikebana), and Sora's father Haruhiko took her surname when they married.
    • Koichi Kimura of Digimon Frontier was raised by his divorcee mother, and thus has her surname. His identical twin brother, Koji, was raised by their father and goes by their original surname, Minamoto.
  • In Fresh Pretty Cure!, Miki/Cure Berry's parents are divorced, so she goes by her mother's surname Aono, while her brother Kazuki goes by their father's last name, Ichijou. This helps with their ongoing tendency to pretend they're lovers rather than siblings in order to ward off any unwanted suitors for Miki.
  • In Fullmetal Alchemist, the Elric brothers are registered under the name of their mother, Trisha Elric, rather than their father, Van Hohenheim. This is partially because Hohenheim doesn't have an actual surname, as Homunculus (AKA Father) named him when he was previously only named Slave Number 23.
  • In Great Pretender, Makoto uses his mother's family name, Edamura, instead of his father's, Ozaki. While his reasoning is never explained in-series, his father is a notorious child trafficker whose infamous crimes completely tainted Makoto's chance at a normal life, since no one would hire him due to his relation to a horrible criminal. He likely wanted to distance himself from his father's crimes.
  • Brad and Luke of Green Blood use their mother's surname, Burns, instead of their father's, King. This is due primarily to the fact that Edward King killed their mother, and Brad's goal from the start of the series and later Luke's is to find and kill Edward.
  • In Naruto, the titular character has his mother Kushina's maiden name, Uzumaki. Reasoning for this varies among the fandom, but the most commonly accepted theory, which is also the likeliest to be true, is that it was done to protect him. His father was the Fourth Hokage, Minato Namikaze, and he had many enemies; that was one of the main reasons why Naruto was never told about his parents.
    • Interestingly, Uzumaki turns out to be a more important name in the history of shinobi than Namikaze, as it is not only also the surname of Nagato, but also one of the four major clans descended from Princess Kaguya, others being Senju, Uchiha, and Hyuuga..
    • Kiba and Hana Inuzuka got their surname and abilities from their mother. Kiba mentions at one point that his father walked out on the family because he was scared of Tsume. It's not an entirely unjustified reason.
    • Hagoromo Otsutsuki, the Sage of Six Paths, and his brother, Hamura, inherited their surname from their mother, Kaguya. Considering Kaguya was basically a Physical God while their father was a surnameless Muggle (at least in the anime), this is justified.
  • Portgas D. Ace of One Piece uses his mother Portgas D. Rouge's name instead of the name of his father Gol D. Roger, feeling he owes her greatly while the fact of who his father is has caused him nothing but grief. This also hides the fact that he and Luffy are neither full-blooded nor even half-siblings; Luffy's grandfather, Garp, and Roger were worthy opponents and Fire-Forged Friends, and Roger asked Garp to take care of Ace before dying.
  • The main character of Oishinbo, Yamaoka Shiro, is the son of famous artist and gourmet Kaibara Yuzan but took up his mother's surname because of his beef with his father.
  • Ouran High School Host Club: The Hitachiin twins inherited their surname from their mother, Yuzuha Hitachiin. Not because they are estranged from their father (on the contrary, he is a very kind man), but because the Hitachiin name carries more prestige.
  • Psycho-Pass: Nobuchika Ginoza's surname actually came from his grandmother who is guardian of Tomomi Masaoka, his father. It was never stated when he changed his surname but it stemmed from his strained relationship with his father who ended up becoming a latent criminal.
  • In Saki, it's revealed in the character profiles that mahjong pro Masae Atago kept her maiden name, which means that her daughters, Hiroe and Kinue Atago, got their names from her.
  • Kurisu Makise from Steins;Gate has a different last name from her father, Dr. Nakabichi because of a falling out they had when she was younger and she disproved one of his theories. Later revealed in the first drama CD to be an aversion, since Dr. Nakabachi is not his real name. It's actually Shouichi Makise. Like many examples on this page, this is done to hide their relationship until The Reveal.
  • In the original Japanese version, of Yu-Gi-Oh!, Katsuya Jounouchi's sister Shizuka does this, taking her mother's maiden name Kawai. Their parents are divorced and Shizuka lives with her mother. The 4Kids dub averts this by having Serenity still use Wheeler.

    Comic Books 
  • In Les Maîtres de l'Orge, the American journalist Jay Simpson actually goes by his middle name and his mother's surname. It wouldn't have been so easy for him to approach Julienne if he had gone by his actual name, Christopher J. Texel.
  • In Spider-Man, Peter's clone (who has all the same memories) takes the name "Ben Reilly," the surname coming from Peter's adoptive mother, Aunt May (née Reilly). In this case, it's just a convenient way to hold onto his identity while trying to forge an independent one. (It also helps support the story that he and Peter are just uncannily identical cousins.)
    • Similarly, Peter's Ultimate Marvel successor, Miles Morales and his father, Jefferson like the aforementioned Shinji and Gendo Ikari, go by Rio's last name, rather than Jefferson's original last name, "Davis". Part of this is Jefferson trying to get away from his past as a thug.
    • Recently, Peter's friend Harry Osborn legally changed his name to Harry Lyman, after his mother's maiden name. Given that his father Norman Osborn is an absolute sociopath who tried to have Harry killed to further his own agenda, Harry's desire to distance himself from the Osborn legacy is understandable.
  • Syrin (Theresa Cassidy) went by her mother's surname when she was younger. The extent this went to varies depending on the era and the writer, with even what exactly her mother's last name was being rather fluid. (It was either Rourke or O'Rourke.) Thus Syrin's sometimes referred to as Theresa Maeve Rourke-Cassidy, Theresa Rourke-Cassidy, Theresa O'Rourke, Theresa Maeve Cassidy, etc. Matters aren't likely helped in that she's used her mother's name as a pseudonym.
  • Wonder Woman (Rebirth): Barbara Ann Minerva's father's name was Cavendish. Her mother's name was Minerva. Given his jackassery towards her, it's little surprise she took her mother's name.
  • Rachel Grey in X-Men, formerly Rachel Summers. (Daughter of an alternate future Jean Grey and Scott Summers, at least by what's in print.) However, this is a recent thing, spurred by her feelings about Cyclops's affair with Emma Frost, as for years, she went by "Summers".
    • Her brother (of a sort) from the Age of Apocalypse, Nate Grey a.k.a. X-Man also uses his mother's surname. While this isn't really to do with his father - he had no idea who his parents were, only using it because it was the surname he was given by his creator, Sinister (and it helped distinguish him from Cable, who usually went by Nathan Summers), it is worth noting that he's always been much closer to Jean.

    Fan Works 
  • In The Bridge, the transformed Godzilla III a.k.a Junior is put in a situation where he has to provide a surname. However, he understandably doesn't have one and was adopted. Both because of his adoration of her and his adoptive father not having one, he opts to go by his adoptive mother's Azusa surname, Gojo. It becomes his official surname in Equestrian documents.
  • In the Naruto fic Days at the Namikaze-Uzumaki Household, it's traditional for children to inherit the clan of their father. Because Kushina is one of the few remaining Uzumakis, a prestigious clan, Naruto inherited her clan as the eldest son, while his younger sister Miruku takes her father Minato's last name Namikaze.
  • Fate/Sunny Order: While Shirou kept his last name, his children Ritsuka and Kana took their mother's name "Tohsaka" as it had more prestige and clout than "Emiya".
  • In Final Fantasy VII fic The Fifth Act, Cloud's surname turns out to be his mother's surname since she never got married. This becomes important when the time-traveling Cloud poses as his younger self's paternal uncle, his surname goes unnoticed until Genesis pulls the thread and realizes that Cloud has the wrong surname for a supposed uncle.
  • There are a number of Fullmetal Alchemist fanfics in which Riza Hawkeye uses her mother's maiden name, Grumman, as an alias for various lengths of time and assorted purposes.
  • In the Hotel Transylvania fic How to Zing, when Martha first meets Dracula she gives her mother's maiden name, Laubode. She does this because she's Human, and doesn't want Dracula to track her down. As anyone who's seen the film will know, she will later take this name permanently.
  • In the Naruto story Kitsune no Ken: Fist of the Fox, just like in the canon series, Naruto takes his surname from Kushina, although the reason for it in this continuity hasn't been revealed yet, especially since it's been confirmed that Minato is alive and works for the military.
  • Ash Ketchum in Pokémon Reset Bloodlines has his mother's surname, given that he was conceived in a one-night stand and never met his father. Given the current revelations about the man, it's more than likely that he's far from the only example.
  • In the Zootopia fanfic Take a Stand Nick resents his father, Robin (The Hood) Loxley, for faking his death and fleeing the country when he was only twelve. As such Nick uses his mother's maiden name, though she kept her married name.

    Films — Animation

  • Avengers: Endgame: Variant: When Hawkeye and Black Widow meet the Guardian of the Soul Stone, he greets them as "Natasha, Daughter of Ivan, and Clint, Son of Edith". This is not commented upon.note 
  • Creed: Adonis initially refuses to use his father's surname and goes by his birth mother's surname Johnson. When his rival's agent insists he use the Creed name to promote their fight, he's dismayed and reluctant to agree to it. He eventually learns to accept both names and in the final fight wears a pair of shorts that have both "Creed" and "Johnson" embroidered on them, a gift from his adoptive mother who also happens to be Apollo's widow.
  • The Reveal at the end of Down Periscope is that Brad Stepenak is actually Admiral Winslow's son. He uses his mother's maiden name to avoid patronage and to rebel against his father.
  • In Live Free or Die Hard, John McClane's daughter uses her mother's maiden name Gennero to distance herself from her father; it's a Call-Back to the first film, where John's wife had also reverted to Gennero after she moved to a new job in California.
  • Nothing in Common: David Basner, an ad exec meets, and becomes attracted to, Cheryl Ann Wayne, who works for Andrew Woolridge, an airline mogul whom David is trying to recruit as a client. After the three have a meeting, David and Cheryl go to bed together, after which Cheryl reveals Wooldridge is her father. David has an Oh, Crap! moment because he thinks she's married, but Cheryl explains she used her mother's maiden name when she went into business because she didn't want people to think she only got where she was in business because of her father.
  • In the 1998 version of The Parent Trap, Annie James and Hallie Parker are identical twins. They have different last names because when their parents divorced, they each got custody of one twin, and Elizabeth James chose to give Annie, whom she raised, her maiden name rather than the name of her ex-husband.
  • In Prometheus, it's implied that a falling out with her father, Peter Weyland made Meredith Vickers not use his name.
  • Spectre: Franz Oberhauser resented his father for showing kindness to Bond when he was young, so he took his mother's maiden name, and lived under the pseudonym of Ernest Blofeld. The reveal is foreshadowed a few scenes prior, where he gives Bond a variation of the "No, Mr. Bond, I expect you to die," line, and the appearance of his white fluffy cat.
  • Star Trek Into Darkness features Doctor Carol Wallace, a last-minute assignment to the Enterprise. Spock learns that her real name is in fact Doctor Carol Marcus, having signed onto the mission under a false name to avoid drawing her father's attention.

  • In The 39 Clues book series, Amy and Dan carry their mother's maiden name (Cahill) instead of their father's (Trent). It is eventually revealed that they are part of the Madrigal branch of the Cahill family, who do this as a nod to ancestor Madeline Cahill's devotion to her own mother.
  • Arn: The Knight Templar: Bengt Elinsson uses a matronymic instead of a patronymic because he wants to distance himself as much as possible from his violent, abusive, and alcoholic father. There is a ceremony involved, where he drops his cloak in his father's clan colours, into his dead father's blood, and is wrapped in his mother's colours by her clansmen.
  • In BattleTech Expanded Universe, children born to a royal/noble/prominent mother and a common father will often take their mother's name or hyphenate their name to include both parents. The latter is also done if both parents are high-ranking or prominent people (e.g. Conner Rhys-Monoroe, the Steiner-Davion children). However, there are variants:
    • Harrison Davison declined to use the hyphenated Sandoval-Davion, instead simply taking his mother Yvonne's name, despite the fact the Sandovals are also a high-ranking noble family. This was supposedly because he didn't want the head of the House Sandoval, Duke Corwin, reading too much into it.
      • Harrison's son, Caleb Hasek-Sandoval-Davion, took this trope Up to Eleven by taking his father, mother and paternal grandfather's surnames to empathize that he was a descendant of the three most powerful families in the Federated Suns.
      • Interestingly enough, both Harrison and Caleb declined to take the Steiner name, perhaps to distance themselves from their Lyran heritage or possibly the legacy of either Victor or Katherine.
    • The children of Captain-General Jessica Marik took only the Marik name, despite their father, Philip Hughes, being from a noble family. This is because House Marik are the traditional rulers of the Free Worlds League and its successor states.
  • In the Cal Leandros books, brothers Cal and Niko keep their mother's name, not because they got along with her, but because Cal's father is a nameless monster and Niko didn't meet his until he was an adult.
  • Done by rule amongst the Renunciates of Darkover. In their misogynistic society, they're an organization of women who have managed to obtain most of the legal rights of men, but to do so each woman must foreswear any traditional feminine prerogatives, such as those given by marriage or wealthy/noble birth. This includes being known by a father's or spouse's name. Renunciates are known as "name, daughter of (in local language, this is n'ha) mother's name." Jaelle n'ha Melora and Margali n'ha Ysabet are point-of-view characters in several novels.
  • In the Discworld as perceived by A.A. Pessimal, the canonical In-Universe truth is that a Witch takes her mother's name. Always. Thus the magically-inclined oldest daughter of Wizard Ponder Stibbons drops his name and becomes Rebecka Smith-Rhodes. There are inversions: Sam Vimes wonders why his Witch Policewoman Olga Romanoff retains the family name of her father's side. His butler Willikins explains daughters of the nobility cannot drop their family title just like that, even when they are Witches. There are practical considerations too:
    I understand Captain Romanoff's mother was originally called Ekaterina Alexeyevnya-Petrovnichniya-Volovovnya of Novo Chechovinitnia, prior to her marriage to Grand Duke Nicholas Romanoff.
  • In the Doctor Who Expanded Universe novel The Wheel of Ice, Josie Laws MacRae, whose mother's maiden name was Josephine Laws, drops the MacRae at some point prior to the birth of her daughter, Joss Laws, due to her pride in the Laws family history. Joss and her daughter Jo seem to keep the Laws name when they get married.
  • Family Skeleton Mysteries: Nelson Paul Mannix is revealed in book 3 to go by his mother's surname after a falling-out with his father.
  • Played With in The House of Night: Upon learning that she can change her name in the House of Night, Zoey uses her mom's maiden name, Redbird, because her grandmother is the only family member that she likes.note  Prior to this, she had her Disappeared Dad's surname, while her mom and siblings all took her stepfather's.
  • In Tamora Pierce's The Immortals series, Daine starts the story not knowing who her father is, thus leaving her with no choice but to go by the name Sarrasri, or "Sarra's daughter", which marks her as a bastard child. In the fourth book she finds out her father is Weiryn, God of the Hunt and briefly considers changing her name to Weirynsra before deciding that she'd been through so much with her mother's name and that she should keep it.
  • In The Mortal Instruments: When Clary was born, her mother had just escaped from a war in which she was on the morally questionable side and a husband who murdered her parents. Up until she moved to New York, Jocelyn still went by "Jocelyn Morgenstern", but then made the conscious decision to change Morgenstern to Fray, a portmanteau of her maiden name, Fairchild, and Tessa Gray's surname, since the latter helped her start a new life. Clary decides to go by Fairchild instead of Fray upon learning her heritage but is still occasionally referred to as "Clarissa Morgenstern", despite her dislike of the name due to her vendetta against Valentine.
  • In One Flew Over the Cuckoo's Nest, the Metis narrator is named Chief Bromden. He inherited "Chief" from his Indian dad, Chief Tee Ah Millatoona, but "Bromden" from his white mom.
  • In the Vorkosigan Saga, Miles Vorkosigan uses his mother's maiden name in his secret identity as Admiral Miles Naismith. Per Naismith's cover story he is a clone of M. Vorkosigan, hence of the same genetic offspring and hence legally entitled to the name. Additionally, even in his non-cover identity Miles Vorkosigan's middle name is Naismith, as a substitute since his paternal grandfather forbade that he should be named after him.

    Live-Action TV 
  • Arrow:
    • Oliver Queen's children, William Clayton and Mia Smoak, both took their mothers' last names; in William's case, they weren't married; in Mia's case, she didn't want to be associated with their vigilante father. Both of them eventually avert this in some way: William changes his last name to Harris for anonymity, matching neither parent, and Mia retroactively goes by Oliver's last name after his death in Crisis on Infinite Earths, which caused Oliver to be recognized as a hero. William is also back to Clayton in that timeline.
    • Felicity Smoak was born and raised as "Felicity Kuttler", her father's last name. She used to be close with her father, a hacker who is even more talented than she is and inspired her to learn more about the profession, but he abandoned the family when she was seven. In reality, he was forced to leave because his wife thought he was a bad influence on their daughter. While Felicity eventually reconciles with him, she continues to go by Smoak.
  • Criminal Minds: Temporary BAU Analyst Ashley Seaver uses her mother's maiden name because her original last name belongs to her serial killer father. Since she assumes the team already knows, it's probably due to her rejecting him, rather than an attempt to hide their relationship.
  • On Doctor Who, River Song's birth name Melody Pond is from her mother's maiden name. Amy named her that way because "Melody Williams is a geography teacher. Melody Pond is a superhero." Her father is often called Rory Pond by the Doctor, anyway, even though he didn't take his wife's name officially.
  • The Flash: Barry learns from his father, Henry, that "Garrick" is the maiden name of Henry's mother. It seems weird that the Flash from Earth-2 also has that name. As it turns out, "Jay Garrick from Earth-2" is an impostor, while the real Jay Garrick is from Earth-3 and looks exactly like Henry Allen, implying that he's a version of Henry who took his mother's surname rather than his father's.
  • On Gilmore Girls, Gilmore is Lorelai's maiden name and the one she gives to Rory. The reason given for this was Lorelai naming Rory after herself while high on painkillers and thinking it was a Double Standard that men can do that with sons, but it's uncommon for mothers to do that with daughters ("Rory" being short for "Lorelai"). Although this is seen now as Early Installment Weirdness since in later seasons, Lorelai is revealed to have been named after her grandmother, whose last name is also Gilmore. This technically makes Rory Lorelai Gilmore III. However, this choice also highlights Lorelai's independence and Christopher's lack of involvement.
  • Micah Sanders on Heroes has his mother Niki Sanders' last name rather than his father DL Hawkins', although his parents are married and his father's side of the family seems more functional than his mother's. A specific reason is never given, but they might have changed it after his father was framed for large-scale robbery and murder.
  • Law & Order: Organized Crime: The children of the Big Bad are Dana and Richard "Richie" Wheatley Jr. Their paternal grandfather was Manfredi Sinatra. His son, Richard, changed his name just to spite his father.
  • Referenced in My Family when Susan says she'd like to be Susan Ryman. "Harper is my husband's name, Riggs was my father's name, but Ryman was my grandmother's name. She chose it herself, no men involved."
  • When Madge reverted to her maiden name — Ramsey — after divorcing Fred Mitchell in Neighbours, their son Henry changed his name to Ramsey as well.
  • In Riverdale episode "Dog Day Afternoon", Veronica considers changing her last name from her father's (Lodge) to her mother's (Gomez), because of the criminal implications associated with the Lodge name. She ultimately decides not to.
  • Stargirl: The titular character was raised solely by her mother, Barbara Whitmore, until the latter married Pat Dugan, since her biological father, Sam Kurtis, was a deadbeat. And it's unclear they were even married. As a result, she's known as Courtney Whitmore rather than Courtney Kurtis.
  • In the pilot episode of That Girl, Anne Marie considers using her mother's maiden name as her last name because - per her agent — everyone thinks "Marie" is her middle name. "Anne Marie what?"

    Mythology And Religion 
  • Loki Laufeyjarson in Norse Mythology. His father's name is actually Farbauti, while Laufey was his mother. Why he uses a matronymic instead of a patronymic is unknown; since the stories were usually told orally, many believe that it's just for alliteration.

    Video Games 
  • In Alpha Protocol, Madison Saint James uses her mother's maiden name after having a falling out with her father, Alan Parker.
  • Assassin's Creed IV: Black Flag has Jennifer Scott, Edward Kenway's daughter with his first wife Caroline, decide to keep using her mother's surname even after she reconnects with her father and begins to live with him since she was solely raised by her mother and never even met her father until after her mother had already died. Unusually for this trope, Edward's relationship with Caroline seems to be amicable, and Edward seems to approve of Caroline's choice to honor her mother.
  • Troy and Tyreen Calypso, the antagonists of Borderlands 3, use their mother's name.
  • Mio and Mayu Amakura of Fatal Frame II have their mother Shizu's last name, though they didn't adopt it themselves—their father Misao took his wife's name when they married, as he wanted to distance himself from his birth surname, Asou.
  • In Final Fantasy VIII, Rinoa Heartilly goes by her mother Julia's maiden name to disassociate herself from her father, Fury Caraway, who is a general in the military of the same nation she's a member of La Résistance against.
  • A variation in Fire Emblem: Three Houses, where Claude's surname, von Riegan, is technically one, as his mother threw away her ties to the Riegan Dukedom by running away to the neighboring kingdom of Almyra and marrying its king. Upon discovering his mother's heritage, he took up both the von Riegan mantle along with a Naturalized Name (his birth name being Khalid, as revealed in an interview) in order to bring his dreams of easing tensions between both Fodlan and Almyra to fruition.
  • In the Homestuck Gaiden Game Hiveswap, Joey goes by her deceased mother's surname, Claire, rather than her estranged father's surname, Harley. Her brother Jude holds much less resentment towards their dad and still goes by Harley. Before the game's release, this trope kept secret that any of the game characters had any relation to characters from the comic, where Mr. Harley is a fairly important side character.
  • Meryl Silverburg of Metal Gear uses her mother's last name rather than her father's for unknown reasons.
  • Jun Kurosu, of Persona 2, uses his mother's maiden name in the former game of the duology, Innocent Sin, after his parents' nasty divorce, and his father's death, although it's unclear when his name was changed, and whether it was his decision or his mother's. In the sequel game, Eternal Punishment, which takes place in an alternate timeline, his parents are both alive and Happily Married, and so he retains his father's surname, Kashihara.
  • Spider-Man (PS4) sees Miles Morales be an even truer example of this, as, unlike the Ultimate Universe, his dad Jefferson still goes by "Jefferson Davis" in this universe.
  • A variation in Tales of the Abyss where Guy Cecil uses a slightly different version of his mother's maiden name as a cover for his true heritage.
  • Jin Kazama of Tekken uses his mother Jun's surname. Given his ugly relationship with his father and grandfather, that isn't surprising.
  • Chloe Frazer from Uncharted specifically says she uses her mother's surname when it's noted that it's not an Indian (where her dad was from) name. Why she uses it instead of his name is never explained, however.

    Visual Novels 
  • In Fate/stay night and the prequel series Fate/Zero, Ilyasviel von Einzbern is only ever referred to with her mother Irisviel's family name, which helps hide the fact that she's Kiritsugu Emiya's biological daughter and therefore Shiro's stepsister. It's implied to be part this trope since she believes that her father abandoned her (in reality, he tried to get back to her before he died but was prevented by Ilya's grandfather, who hated Kiritsugu for his actions at the end of the Holy Grail War) and because the von Einzbern family is a very powerful and ancient magus family compared to Kiritsugu's.
    • Her alternate self in Fate/kaleid liner PRISMA☆ILLYA keeps the trope for some reason, despite being a normal girl whose parents (who are still alive) had broken ties with the main von Einzbern family. Doubly confusing with the fact that Shirou took on Kiritsugu's surname upon adoption.
    • Caren Ortensia in Fate/hollow ataraxia also uses her mother Claudia's surname because her father, Kirei Kotomine essentially abandoned her after Claudia died via committing suicide. Like with the above this is used to hide their relationship from the viewer until the appropriate time.
  • In Kara no Shoujo, one of the missing girls that the main character is investigating, Nishizono Yui, took her mother's last name after her parents' divorce. Discovering her true surname, Kusaka, is what clues Reiji in solving the first dismemberment case.

    Web Animation 
  • RWBY: Taiyang Xiao Long has two daughters by two different women, Yang Xiao Long and Ruby Rose. His first wife, Raven Branwen, abandoned the family when their daughter, Yang Xiao Long, was a newborn. His second wife, Summer Rose, raised Yang as her own but died while Yang and Ruby were still very young. While Yang uses her father's name of Xiao Long, Ruby goes by her mother's name of Rose. Due to a past world war that attempted to suppress individuality and artistic expression, the world considers it a very serious matter to ensure that children have names that allow them to express themselves artistically. It's therefore very strongly implied that Ruby chose to use her mother's name, as she has incorporated the rose into her personal design, wearing a red cape that sheds like rose petals, and using a rose as her personal symbol, which is woven into her stockings and prominently displayed as her cloak clasp.

  • Abstract Gender: A couple of years after Ryan was born, his father left... but before going, legally changed his son's last name to his mother's maiden name.
  • Kimiko Ross of Dresden Codak was originally Kimiko Kusanagi, but changed her name after she was estranged from her father and her mother died suddenly. In the timeline of the story, she sees her father again briefly (and flips him off from her hospital bed), but sometime after this, he dies and she continues going by her mother's surname, even when it would probably help her career to use her father's name because of the renown associated with him in the city of Nephilopolis, which he actually founded. Ironically it's eventually revealed Kusanagi isn't his real name either, he was born Kim Young-Soo and isn't even Japanese, but Korean. So Kim has been using his name for herself without realizing it.

  • In The Legend of Korra, a Sequel Series to Avatar: The Last Airbender, both of Toph Bei Fong's daughters, Lin and Suyin, use her last name.

And similarly, former Prime Minister of Spain, José Luis Rodríguez Zapatero, usually went by his mother's name "Zapatero" rather than his father's name Rodríguez, but because of issues he and his mother had with his father. Formula One legend Ayrton Senna da Silva chose to go by his mother's name of Senna because Silva is a very common name in Brazil (as well as Portugal). More recently, Mexican filmmaker Alejandro González Iñárritu now credits himself in English as "Alejandro G. Iñárritu", presumably because his mother's family name is much more distinctive than his father's.

  • Prince Philip, the Duke of Edinburgh, was born Prince Philip of Greece and Denmark, a paternal grandson of George I, King of the Hellenes. Before marrying the future Queen Elizabeth II in 1947, he became a naturalized, non-royal British citizen, for which he needed a last name. The problem? The Greek royal family doesn't actually have one (the closest would be the royal Danish name of Schleswig-Holstein-Sonderburg-Glucksburg, which would have completely defeated any attempt at becoming 'more British')note . Eventually, it was decided Philip would use the name his mother's English (well, Anglicized German) family had adopted — Mountbatten (a "translation" of the original family name "Battenberg"). Interestingly, his mother never used the surname herself as she had already married into the Greek Royal Family by the time they anglicized their name during World War I.
