Rav Aryeh Yehuda Leib Epstein (Leibush the 2nd) of Oztrov (1852-1928), son of Rav Yechiel Chaim of Oztrov and grandson of Rav Aryeh Yehuda Leib HaLevi (Leibush HaGadol), founder of the Oztrov dynasty. In his early teens, he married Rebbetzin Draizel, who herself learned Gemara and personally tested their five sons. Rav Leibush succeeded his father as Rebbe in 1888. His most famous follower was Rav Meir Yechiel HaLevi Halshtok of nearby Ostrovtza. Rav Leibush was succeeded by his oldest son, Rav Avraham Shlomo, whom in turn was followed by his son Rav Moshe Yechiel HaLevi Epstein (the Aish Das of Oztrov, 1890-1971). Save for its 350-year old cemetery, nothing remains today of the town of Oztrov.
