I don't have big family trees. What I end up.doing is making relatives that end up in the stories right from the outset. Which ends up making my game go "oh hell no! Not this again" but what legacy is without uncles, aunts and parents of the founder generation? Hence my legacy tends to have a pre-founder generation which pretty much makes the game huge from the outset.
Plus they're an "Asian family"; we tend to breed like rabbits. ?
Okay, clarifying; with the McIrishes as family they're mixed.
Yes, there's a reason why I use River. Same family background as my real wife @Featherbelle : raised by mother only, didn't know where dad ran off to.
