At what point in a person's family history do their ancestors stop being what they used to be and start being who they presently are?  My family tree has always been a little unclear to me.  My parents have information about some family members going back to around the mid-1800s, but before that it's muddy.  And the information they have is that my ancestors have been born and raised in America for at least four or five generations.  Their surnames aren't overtly Italian or Irish or German, and we're not black or Asian, so I'm probably a mixture of various breeds of British.  But I'm not British.  And my parents and their parents aren't British.  So at some point in time, my ancestors stopped identifying themselves by their history.  And that was likely the case for my ancestors' ancestors, who went to England by leaving some other ancestry behind.  And so on.  Modern human civilization likely started in Africa, so we're all technically Africans.  But what about before that?  Primordial oozians? #lifestyle
