Historical Character's Fictional Relative

Beck: It's at a friend, Peach Salinger's.
Joe: Like J. D. Salinger?
Beck: I mean, yes. But she doesn't like to talk about it. And she's a sweetheart. Her family's just a little, you know?

— You (2018)

A fictional character is revealed to be related to someone non-fictional and famous. Sometimes, this is supposedly a distant ancestor (for instance, Alice claims that she is the great-great-great-great-granddaughter of Napoléon Bonaparte) while at other times the relationship is much closer in terms of blood. If that non-fictional celebrity is still alive, they might actually turn up as a guest star playing themselves.

Not to be confused with Real-Life Relative (or Relatively Flimsy Excuse, which deals with in-universe fake relatives) or Fictional Fan, Real Celebrity, where a fictional person is connected to a known famous person, but through fandom rather than family. See also Historical Domain Character, Famous Ancestor, Same Surname Means Related, Crossover Relatives, History with Celebrity, and Beethoven Was an Alien Spy.

• Subverted in Lamarckian. The villain Wendigo is introduced as being a descendant of Andrew Jackson (who had no children) and tries "finish what he started" by hunting Native American populations.

Note that the author was well aware this theory was highly fanciful, but it certainly made for a better story.

In the first series, Percy is identified as the Duke of Northumberland and in the second series, he's Lord Percy Percy, the heir to this title.

At the end of the series, Pullo is charged with executing Caesarion on Octavian's orders, but instead he spirits him away and raises his son in Rome.

Music

• The Arrogant Worms' song "Jesus' Brother Bob" is sung from the perspective of the brother of Jesus. (Presumably half-brother, both having the same mother Mary.) It details the complaints of Bob being overshadowed by his famous brother. Among his gripes is when mobs of people (typically played by the audience) come beseeching the help of Jesus, they leave disappointed when they find it's "only Bob". A more humorous one is that Bob needs to pay for the Sea of Galilee ferry, whereas his brother can simply walk across at no cost. In later performances of the song, about the only person who pays much attention to Bob is Judas, though even then, to Bob's annoyance he's mostly just interested in how Bob's family's Christmas was.

Video Games

• Assassin's Creed:
  • In Assassin's Creed II, Ezio's teenage girlfriend, Cristina Vespucci, is the cousin of explorer Amerigo Vespucci.
  • Assassin's Creed IV: Black Flag subverts this: when the character James Kidd first appears, it's directly stated that he's the son of Captain Kidd, if the name wasn't enough of an indicator. The subversion is that not only is Kidd not really a Kidd, he's not fictional and isn't even a man—it's a persona played by the historical lady pirate Mary Read as part of her Assassin activities.
  • Assassin's Creed: Odyssey has it that the player character, either Alexios or Kassandra depending on player choice, is the grandchild of King Leonidas — yes, that Leonidas, the one also featured in 300 — through his fictional daughter Myrrine, whereas in actual history Leonidas is only known to have had one child, a son named Pleistarchus; spotty historical records are used to justify this, like most liberties taken in Assassin's Creed. It's also eventually revealed that Alexios and Kassandra's biological father is actually Pythagoras, the famed Greek mathematician, not their recognized father Nikolaos as detailed early in the story, doubling-up on their known historical relatives.
• In Aviary Attorney, main character Jayjay Falcon is the grandson of Maximilien Robespierre, which he has gone to great lengths to conceal.
• The Big Bad of Ghost of Tsushima, Khotun Khan, is the grandson of Genghis Khan and cousin of Kublai Khan.

  • Yuyuko Saigyouji is implied to be the daughter of the famous Japanese poet Saigyou.
  • Byakuren Hijiki is the sister of the historical Buddhist priest Myouren Hijiri.
  • Fujiwara no Mokou was the daughter of a Fujiwara noble of high enough rank to be a princess's suitor.^note The most likely candidate is considered by fans to be Fujiwara no Fuhito, son of the Fujiwara clan's founder. Which in turn would mean that the founding heads of each of the Fujiwara clan's primary branch families were Mokou's brothers. There's no historical record of the name of Fuhito's fifth and youngest daughter, meaning there's no evidence she wasn't Mokou. However, due to the princess humiliating her father by refusing his proposal, Mokou swore revenge, drank the Hourai elixir she was supposed to destroy, and now fights Kaguya whenever she can (since both are immortal).
  • The relation between Yukari Yakumo (one of the oldest and most powerful youkai in Gensokyo, able to do whatever the hell she wants with boundaries) and Maribel Hearn (a young girl who can see boundaries) is uncertain, but fanon generally accepts that Yukari was Maribel very (very) long ago, despite existing in the same time period (which, admittedly, means very little in Gensokyo). When asked about this, Zun only said "There once was a man named Lafcadio Hearn" (Lafcadio being a 19th-century Irishman who eventually settled in Japan ad collected traditional ghost stories, taking the name Koizumi Yakumo).
• Nathan Drake from the Uncharted series claims to be descended from Sir Francis Drake, though it later turns out he lied about that.

Webcomics

• PepsiaPhobia: Phobia's (possibly half-)brother is Alcides, better known (after the bout of divine madness during which he killed his family) by the name Herakles.
• Giuseppe the pizzeria manager in Irregular Webcomic! has a tendency to assert his expertise in something with the Mad Libs Catchphrase "I'm a direct descendent of [historical Italian known for that subject]! Italians invented [that thing]!" Assuming this is true, he's a direct descendent of Alessandro Volta, Giovanni Casanova, and Augusto Righ, making him an expert in electricity, love, and microwaves.

Web Videos

• Headless: A Sleepy Hollow Story: Real-life explorer Henry Hudson is given a wife named Henrietta Hudson, who captained one of the ships in the same fleet and was the leader of a witch coven, before getting turned into the Headless Horseman.
