Good to see you still digging on this. There may be gold in those hills. An anon posted this, it might tie in somewhere:
"In human genetics, Haplogroup E (M96) is a human Y-chromosome DNA haplogroup. This haplogroup is found in Africa, the Middle East, and Europe. Haplogroup E is found in Africa, Asia and Europe and it is divided into three clades: E1 and E2 are found exclusively in Africa, while E3 is observed in Africa, Europe and western Asia. E3 is further divided into E3a and E3b, but only E3b is observed in significant frequency in Europe and western Asia in addition to Africa. E3b is estimated to be 25 600 years old. [1] Most Sub-Saharan Africans belong to E(xE3b), while most non-Africans belong to the E3b clade of the E haplogroup.”
