In the late 19th century, the descendants of Reb Moishe Leib of Sassov had become rabbis in other cities. The town people found themselves without a Rebbe. They approached the Sar Shalom of Belz for guidance as to whom to appoint as Rebbe. He advised them to nominate Reb Shlomo of Sassov, who became a great leader in his own merit.
There is a Sassover Rebbe in Monsey, New York, Grand Rabbi Yaakov Tzvi Erblich, who is a son of Grand Rabbi Moshe Yehudah Erblich (d. 1991), Sassover Rebbe, son of Grand Rabbi Yaakov Tzvi Erblich, Porosover Rebbe, son of Grand Rabbi Yekusiel Shmelka Erblich (1800–1861), son of Rebbe Moshe Leib Sassover (1745–1807), founder of the Sassov dynasty.
Rabbi Lipa Meir Teitelbaum, was the Sassov-Keretzky Rebbe. He was the son-in-law of Rabbi Joel Teitelbaum of Satmar. He was succeeded by his two sons: Grand Rabbi Yoseph Dovid Teitelbaum who is the Sassover Rebbe in Kiryat Yismach Moshe in Ganei Tikva, in Israel, and a son-in-law of Grand Rabbi David Moshe of Kretchnif. He was a disciple of the previous Klausenberger Rebbe. His brother, Rabbi Chanoch Heynach Teitelbaum is the Sassover Rebbe in Monsey, New York.
