Mg: "I think what is saddest about this is that it is basically cousin against cousin, family against family."

Must say I find this melodramatic tawddle. You don't *seriously* consider yourself "cousin" with people that you shared a common ancestor with of several generations ago...? 'Family' isn't a few shared chromosomes, it's the people you are close to and share love and arguments with.

Say someone from Australia tracked me down after my great great Uncle emigrated in 1918, I'd think it jolly interesting. But only that - I sure wouldn't feel any kinship based on the fact that we shared a great great great granny that neither of us ever knew. And there wouldn't be any tearful reunion with lost "cousins" ten times removed.
