Hello all
One of the question which comes often is how far DNA can trace a portuguese ancestor at least 8 generations ago ?
I remember having read that it is not possible but I cannot put a hand on the article.
In other terms do you all agree that if I am 100% askenazi this does not mean that at 8 th generation away my ancestor could not have been 100 % descending from jews who escaped Portugal after the inquisition ?
Thanks

Focussed today on my ancestors from Emden and Groningen region and in particular Portuguese ancestor (Henriques, Mousaphia line from Gluckstadt and Hamburg)
