History Main / IAmXSonOfY

* Iceland is the only land in the western world where people commonly don't have surnames, with some few exceptions, mostly for foreigners. To tell each other apart, people add X, ''son of Y'' or ''daughter of Y'' ("-son" and "-dóttir," respectively) to their names. It's however not a surname and people address each other and are listed in phone books by their given names. And addressing someone by their patronym or matronym is culturally insensitive. The president should be called Ólafur, Ólafur Ragnar, or Ólafur Ragnar Grímsson, never just Grímsson. The former president should be called Vigdís or Vigdís Finnbogadóttir, never just Finnbogadóttir.

Until the latter half of the 20th century, it was generally accepted that openly bearing your father's or culture's good name as a badge of honor was perfectly acceptable behavior, as it showed [[ThickerThanWater filial loyalty to one's roots]]. Not only was "Son of Y" basically your surname in ancient times, but UsefulNotes/{{Patronymic}} surnames are also where many modern last names come from ("Jacob'''son'''", "'''Mac'''Donald", "Alexey'''ev'''", "Ivan'''ovich'''", "'''bin''' Tariq", "Gonzál'''ez'''" and "Giann'''opoulos'''" for example).

** ''Film/{{Solo}}'': Chewbacca introduces himself to Han, in the Wookiee tongue, as "Chewbacca, son of Attichitcuk." This is only clarified in the script and novelization.

* ''Literature/ByTheWatersOfBabylon'': The protagonist declares himself "John, son of [[AncestralName John"]].

* The ''WesternAnimation/HowToTrainYourDragon'' fanfic ''Fanfic/AThingOfVikings'' uses this trope on occasion. Hiccup's full name in this story, for example, is "Hiccup Horrendous Stoickson of Clan Haddock".

** Also in ''The Odyssey'', the recurring formal way of addressing the hero is "''diogenes Laertiade, polymechan' Odysseu''" or "Son of Laertes, sprung from Zeus[[note]]For Odysseus that was not just flattery: his mother was a granddaughter of Hermes, son of Zeus.[[/note]], Odysseus of many devices" (translation by A. T. Murray).

* As mentioned above, Arabic names also get this treatment, with ''ibn'' or ''bin'' used for sons and ''bint'' used for daughters.

* The "Mac" in Scottish and Irish surnames means son.

* ''Manga/TimeStopBrave'': Kuzuno Sekai meets a woman who introduces herself as "Sayuki Takegawa, daughter of Aritsune Takegawa."

* In ''Film/The13thWarrior,'' Antonio Banderas' character introduces himself as "Ahmed Ibn Fahdlan Ibn Al Abbas Ibn Rashid Ibn Hamad," where "Ibn" means "son of". The Norsemen he's talking to conclude his name is "Eben".

** ''Film/AvengersInfinityWar'': Variant; the keeper of the Soul Stone greets people by lineage. "Welcome Thanos, son of A'Lars, and Gamora, daughter of Thanos." It underlines the keeper's mysticism, since he's sitting alone on a planet in the middle of nowhere.
** In ''Film/AvengersEndgame'', he greets [[spoiler:Black Widow and Hawkeye as "Natasha daughter of Ivan, and Clint, son of Edith." Hawkeye dismisses this as a parlor trick, but Black Widow is shaken since ''she'' didn't even know her father's name]].

* Practically overlaps with BadassCreed and possibly CatchPhrase in ''VideoGame/Disgaea2CursedMemories'' -- "I am Rozalin, the only daughter of Overlord Zenon!"
