converted to
Judaism ? I think G is the origin but some tribes from Arabia came on that area as invaders some semitic tribes must have adopted the Judaism ?
The oldest Sepharadic Jewish presence in Europe seems to be Ibiza with a high frequency of G2a3b1 in this community. G is found both among Ashkenazi and Sephardic that's makes me think that the first Hebrew were G this is matching with the Hurrian - cauacasus origin of the first Mesopotamian tribes . A cluster of closely related Ashkenazi Jews represent virtually all confirmed G2c persons worldwide, both from private testing, and from academic studies.
Concentrations of G2a3b1 at Certain Sites :
The highest percentage of G2a3b1 persons in a discrete population so far described is in the island of IBIZA off the eastern Spanish coast. Ibiza samples include indentifiable persons from the DYS388=13 subgroup. Because value combinations of the STR marker samples in Ibiza are also common in
Sephardic Jewish samples,
[8] the haplogroup G in Ibiza might be related to the significant population of
Crypto-Jews in Ibiza.
