He is my great-grandfather (4), apparently there is a family connection between him and the mother of Rabbi Avraham BORNSTEIN, 1st Admur Sochaczew
Rabbi Avraham Bornstein, 1st Admur Sochaczew
His father may have been
Mordka Erlich
And it is possible that he also used the last name Kober, which is probably his wife's last name
Since I am prohibited from receiving DNA matches, any information, even the smallest, would help me continue my research in this field
Many Thanks
