Well, the genographic site had the results of my DNA analysis up yesterday, and I may be no wiser than before. This was the attempt to trace my paternal line: son to father to grandfather, and so on. The sad news: no evidence of anything but the typical European markers, so no evidence for a Cherokee heritage. On the other hand, the alleged ancestor was my father's MOTHER'S father -- by definition outside the link of father to son. But if I go to the maternal line, I still wouldn't catch him. I may need a different kind of DNA analysis after all.
