Sasregen (Hasidic dynasty)

Sasregen is one of many offshoots of the Ropshitz Hasidic dynasty that were re-established in New York City after World War II by surviving descendants of Grand Rabbi Naftali Tzvi Horowitz, the first Ropshitzer Rebbe; others include Beitsh, Dolina, Dombrov, Dzhikov, Melitz, Shotz, Strizhov, Stutchin, Sulitza, and Tseshenov.^[1]

The previous Sasregener Rebbe was the son of Rabbi Jacob Israel Jeshurun Rubin (30 Kislev 5645 [December 18, 1884], Zhydachiv, – 15 Sivan 5704 [June 6, 1944]),^[2][3] av beis din (head of the rabbinical court) of Solitza and Sasregin, Romania,^[4] who was murdered in the Auschwitz concentration camp,^[5] and Alte Nechama Malka Dachner, daughter of Rabbi Chaim Dachner of Seret, who was also killed in the Holocaust. His two brothers were also rabbis.

Rubin married Mirl Eichenstein, daughter of Rabbi Joshua Eichenstein. Their eldest son, Rabbi Yehoshua Rubin, is the Bobover Rav of 45th Street, and son-in-law of Grand Rabbi Naftali Halberstam of Bobov. The Sasregener Rebbe was the author of Kol HaMikra'ot ShebeTalmud Bavli, which he began in 1955 and published in 1987.^[6]
