“My wife is a distant cousin of baseball star Rogers Hornsby descended from a common half-sister of Pocohantas . . . and more than a century later, we have common Cherokee ancestry which married into settler line on the Georgia/Carolina/Tennessee frontiers. There are remote areas still with size able Cherokee populations who escaped the forced removal in 1838 either because (a)they were sufficiently intermarried with settlers or (b)in locations too remote and/or numbers too few to bother with rounding up.”
Does this Cherokee lineage show up in your wife’s DNA?
We supposedly via written documentation have lineage with your wife’s ancestor and her father, uncles and aunts. Yet zero DNA showing any Indian blood in our DNA.
To get back to the early 17th century, you would have to go back at least three more generations or 1/1024th.
We've had a few other recent topics about ancient DNA, sample links from the helixmakemineadouble keyword:
Great-great-great-great-grandparents, down to you. Most people have 23 chromosome pairs, which means that at least 18 of the gggg-gr generation didn't pass any of their genome to you, assuming there are no duplicates for that generations (because of criss-crossing lines of descent). The cell over the middle 46 is just an illustration, not to show which ones were and were not, since there's (probably, usually) no way to know exactly, short of the unlikely event of having genetic samples from all of one's gr-gr-gr-gr-grandparents.
I just assigned the numbers arbitrarily, as this is a simple model version, and it doesn't take into account, uh, recursive branching (my parents have common ancestors, but none of that fell down through the pinball machine of my genome). Obviously there's no way to have an even break between sides of the family, apart from one's own parents, due to the 23 chromosome pairs. There has been at least one nitwit who claimed that everyone was exactly one quarter of each of their grandparents -- apparently in Nitwitland, the chromosomes play go-fish to make sure it happens, and does this on purpose before each of us is conceived.
