Kretshnif (Hasidic dynasty)
Kretshnif (also written as Kretchinev, Kretchniv, Kretshniff) is a Hasidic Jewish dynasty that comes from the Nadvorna dynasty.
The first rebbe of Kretshnif was Grand Rabbi Meir Rosenbaum, a son of Grand Rabbi Mordechai of Nadvorna. His sons and successors included Rabbi Eliezer Zev in Kretshnif, Romania and Sighit, and Rebbe Issamar of Nadvorna (d. 1973) in Chernowitz. The descendant rabbis of this dynasty span the globe, mainly in Israel, New York City, England, and Canada.
