Last week, Rabbi Yisroel Meir Gabbai of the Oholei Tzadikim Foundation discovered, after a long search, the kever of Rabbi Yosef Yitzchok of Ovruch. Rabbi Yosef Yitzchok was the son of the Tzemach Tzedek, and father in law of the Rebbe Rashab and namesake of the Frierdiker Rebbe.
The kever was found in the Beis Hachaim of Ovruch, which is in a state of great disrepair, and Rabbi Gabbai had a new matzeiva put up.
The Frierdiker Rebbe was named after Rabbi Yosef Yitzchok, who was his grandfather – the father of his mother Rebbetzin Shterna Sara.
Ovruch is located in the Zhitomir Region of Ukraine.
