Khazar has a brand new first name but he did not change the last name because his last name means that he comes from the high class of Jews who claim to be directly descended from a guy named Aaron who was supposed to be the brother of Moses. The Ashkenazi DNA says that they are 100% European – therefore they are not related to Abraham or Moses or Aaron or anybody else in the entire region. But they feel diminished if they don’t hold on to their fake identity by claiming to the Hebrews.
