Rav Yechiel Issomar spent his life immersed in Torah, attaching himself to the great chassidic rebbes of his day. He was a paragon of simchah and pleasantness in his interactions with others.  He was known for playing  Hamavdil and Eliyahu on his fiddle on Motzaei Shabbos . His grandfather was Rabbi  Itamar ben Israel Wohlgelerenter of Konskowola author of Mishmeret Itamar.

He  lived in Ostrowiec until his passing at a ripe old age and  maintained a close connection with the legendary first Ostrovtzer Rebbe, Rav Meir Yechiel Halstock, singing zemiros for the rebbe on Shabbos and Yom Tov.

The children of Rav Yechiel Issamar and Leah Wohlgelernter were Shmuel Yaakov, Reizel, Yisroel Elazar, Yeshayah - father of Chaim Yitzchok and Kalmen.
