I wonder what fraction of the worlds population are descended from Abraham? A lot of generations have come and gone since Abraham died. Every generation you go back you have better odds.
No Jewish ancestors in my family going back 4 generations. Before that? God knows.
Remember that the Jews are just a small portion of the descendants of Abraham.
All those who came from Hagar through Ishmael, from his children with Keturah, and from the 10 northern tribes of Israel who were carried away by Assyria are also descendants of Abraham.
When the Lord promised him descendants as numerous as the sand on the seashore, he meant it.
I don’t know. An estimated 20% of Spanish and Portugese are Jewish by genetics. For example, Penlope Cruz carries the genertic markers.
I did all that when testing for Tay-Sachs before engagement to my wife. Like most Jewish people, I have a common male ancestor.
