We had conversation some time ago regarding the David Davies Eby line.
I did DNA testing on my father before he died--but apparently not the type of testing you mentioned.We used the DNA Ancestry Project which tested the yDNA and mDNA.
However, we did get a pretty good match that way--38/38 with one of the Canadian Ebys who can trace his roots back to Theodorus.The testing indicated a 79 percent chance of a common ancestor within the last 11 generations and 95% within the last 20 generations.My biology background is really limited but as he understood the testing, the connection could be as close as 5-7 generations.Greg is a descendant of Christian, son of Theodorus and he is 8 generations removed from Theodorus if I figured right.
Since that Canadian line traces back to BartlisAebi in Solothurn, SW, seems pretty reasonable to stake out aclaim to heritage from him, now to find out how. . . .
There was also a 20/20 match with a Gordon Dunlop but I cannot find that surname anywhere in the Eby line.
Maybe if others get tested by either program, someday we will get even closer to the truth.I am also still searching out the origin of David Davies Eby/Ebi.
Oh yes, for ancient roots, we also came up with Haplogroup I (M170)
