This is the relevant part of the chart I presented then.
At the Y-67 level, it is clear that our three (identical) Skalat Pikholz descendants came from a common ancestor with a group of Spira descendants. That seemed to indicate that we were Spira not that long ago, likely no earlier than the late 1600s.
But with the Y-111 showing three or four additional mutations, there are two possibilities:
Perhaps the common Spira ancestor was earlier than I had thought and the fact that the 3-4 mutations are all in markers 68-111 rather than markers 1-67.That is easy enough to test. I am a perfect match with two other Skalat Pikholz descendants. All of our earliest known ancestors were born a bit more than 200 years ago. So if I test the other two, I will see if my new mutations are mine alone or more general.
But perhaps some of those new mutations are mine personally, rather than being a general Pikholz thing.
I ordered upgrades for both and the results for the kit known as "Filip" came in earlier this week. (Filip is not the name of the actual tester.)
Filip matches me perfectly at 111 markers. Needless to say, the rest of his Y-111 matches are the same as mine.
So clearly these new three-four mutations happened BEFORE the births of our earliest known Pikholz ancestors - Filip's in ~1795 and mine probably ten to twenty years later. So all of these mutations happened between the Spira-Pikholz split and the late 1700s.
Over how long a period did those three or four mutations occur? Almost certainly beginning well before the late 1600s. It makes the whole "Megalleh Ammukot" descendancy less likely, at least for the Pikholz family, since he was born in 1585.
The third Skalat Pikholz Y-111 upgrade should have results in the next few weeks.
