I know who the 4 women were..

4 women mother the Jews..
The 4 women are clearly Sarah, Rivka, Rachel and Leah (maybe sub Bilha and Zilpa for Sarah and Rivka). I do not understand how they could trace it to 4 women in Europe 2000 years ago.. seems unrealistic. But if you go back to the 4 matriarchs, it makes sense..
