Hello. I am looking for relatives descended from Chaim Joseph Regulant/Ashkenazi and Chaya Rachwalsky. Chaim was born in Kiev. They had five children - Israel (Suni), Pinchas (Phillip), Bertha, Joshua and Tauba/Teible.
Phillip, my grandfather, was married to Rose Rachwalsky. Israel married Ruth, Bertha married Joseph Oberstein, Tauba married Joshua Berenbeim.
We have a large family in Israel and many cousins throughout the U.S.
Good luck with your search.
