Rabbi Avraham Yehoshua Heshel of Apt was the founder of the Apt-Mezhbizh-Zinkover Hasidic dynasty. In honor of the dynasty's founder, his descendants adopted the family name Heshel.
The males in this family took wives several different times from the family of the Ryzhiner Rebbe.
R. Abraham Joshua Heshel of Kopyczynce (1888-1967). His daughter Chava was married to Shneur Zalman Gurary, a chassid of the last two Lubavitcher Rebbes.[1] Their son, Itche Meir Gurary, was asked by some Kopyczyncer chassidim to become a Kopyczyncer Rebbe. However, he chose to remain as mashpia in Tomchei Tmimim of Montreal.
R. Moshe Mordechai Heschel of Kopyczynce (1927-1975) succeeded his father as rebbe, and was renowned for his legendary kindness. He died suddenly of a cerebral hemorrhage.[2][3][4]
