Doesn't work in case of incest. Just thinking of edge cases here...

  Why not? Where someone has more than one relationship to you, you can either mention both or the closer one, as we do in English. "This is my son" (or son and nephew). "Cletus is Hank's father" (or father and grandfather). The suggested tree navigation operators don't rely on the structure being strictly a tree.

    That works if we assume no time travel so we get acyclic graphs. Time travelling incest is beyond the scope of this dsl however.

      Time travel or mountain folk. Banjos can be a funny thing and you never know what'll happen when you strum the ol' hammer claw.

    A relative once said to me "The reason I get on with my aunt so well is that she's also my cousin". Islander life, islander values...

  That isn't even an edge case; some countries have double-digit percentage of consanguineous marriage.
