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 presently 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.
