Hi Marlene - Thank you for sharing your family with me. But, it sounds as though your Katz family is a different one. The Isak Katz I'm speaking of was not originally from Zhuravno, he was born in Rzuchow to Mendel and Lotte Katz. He moved to Zhuravno in his 20s and married a local Zhuravno girl. They raised their family there until they moved to America around 1920.
Best,
Amy
