Luke, I Am Your Index

"For some of this mythical goodness, try throwing relatives of PCs into your campaigns. Imagine if the paladin finds the evil necromancer is her father. Or the grizzled space-freighter captain learns that one of the new crew recruits is the daughter he never knew about. Or two PCs discover they're half-siblings! The dwarf and the elf!"

- Darths and Droids

As The Empire Strikes Back, and god knows how many Soap Operas and Comic Books, have shown, writers love revealing unexpected relations between characters.
