Is it possible to know the parents of a dweller?

I suspect (not entirely sure) that there's something in the game that keeps track of the parents of dwellers born in the vault, and when trying to procreate dwellers, if they're of the same family, they won't match.

If that's true, I'd guess this info is stored somewhere in the save file, and if that's the case, I think it'd be awesome to at least have that info shown to us. I know I completely lose track of who's related to who, and knowing for sure what are the families could be pretty useful for planning the future generations of dwellers.

And, of course, being able to modify that information would also be cool. Or, you know, a button to automagically make everyone not have a family anymore...
