* The driving plot of the movie ''Film/{{Twins}}'' has the main character leaving his island to search for his family, finding a brother, maybe a father, and finally a mother in the process.

* ''VideoGame/MyChildLebensborn'': Since the PlayerCharacter adopted the titular child, the child is an AbandonedWarChild and the child is seven years old, this trope happens by proxy via the PlayerCharacter. The fact that the game also happens in a time and place where Lebensborn children have undergone a major PersecutionFlip is a good indicator of the reaction of the child's biological relatives to being tracked down by the child' current guardian.

** He knew full well where he came from in Literature/TheBible. He killed an Egyptian out of ethnic/nationalistic pride due to not wanting to see his own attacked by an Egyptian wrongly. ''WesternAnimation/ThePrinceOfEgypt'' merely tidies the story up for young viewers, by making that whole murder thing an accident. The idea that he didn't know who he was actually comes from the film ''Film/TheTenCommandments''.

* The title character in Astrid Lindgren's ''Mio, My Mio''.

* A variation occurs in ''Manga/InuBaka'', where Suguri wants to trace her dog's ancestry/pedigree so that she would have a better chance to find good homes for his puppies, should he have any in the future, as people are less willing to take care of a mutt.
* This is Alice's character arc in season 3 of ''Anime/KirattoPriChan''. She was raised in a circus and has chosen to go to Japan to find her parents. She later joins [=PriChan=] in hopes that they might see her shows.

* ''Film/ByHookOrByCrook'': Val, who was adopted by parents who put him in a mental institution for being {{Transgender}}, is trying to find his birth mother. His main strategy, at the start, is going to pay phones and dialing everyone with his birth mother's last name in the phone book.

** In the third arc, [[spoiler:Cricket]] discovers that she was adopted and goes looking for her biological parents, [[spoiler:but she never meets any - one is imprisoned and the other [[FamilyRelationshipSwitcheroo was the dragon she thought was her sister]].]]

* Claire Bennet from ''Series/{{Heroes}}''. Toyed with, in that she does this not out of any sense of insecurity or Wangst, but because she wants an explanation for her immortality. Eventually she finds her biological parents, and [[spoiler:her dad turns out to a be congressman and AloofBigBrother to the man who saved her life: Nathan Petrelli, destined to become President. Nice.]]

* ''Fanfic/TheBridge'' invokes but averts it. Godzilla III a.k.a Junior doesn't have the faintest idea who or where his biological family is or if they are still alive. But when asked if he would ever would want to find his "real family", he casually shrugs it off and displays only nonchalant apathy; citing that his adoptive parents and siblings were the only family he'd want.

->'''Zagreus:''' I'm searching for my mother. You still live at home with yours. You don't know what it's like.
->'''Thanatos:''' Mother Nyx was like a mother to you too. And this is how you repay her. You should be ashamed of yourself and learn your place.

* In ''Series/SingleFather'', Lucy always knew Dave wasn't her real father but it wasn't until her mother died that she felt compelled to find him. The "hunt" is cut shot, however, when Dave discovers that [[spoiler: Rita always knew who the father was, having asked him specifically to help her have a baby (she told her family it was a one-night stand) and had kept in contact with him.]]
