Hellow Herbert, We are relatives. Ben Zion Shaffer (lived in Haifa ,not Jerusalem),(he died many years ago and dealt with dry cleaning),(he was the husband of my father's cousin: Hencha Shaffer (also died a few years ago,and her born Name was Zwirn). Hencha was the daughter of Josehf Zwirn whom I suppose was the sun of Haim +(Haya?) Zwirn from Ndworna (now in Ukraine). Your information confuses me a little, because you say that BenZion Shaffer was from your mother's side, and I know (from information that I got from his daghter that her mother - Hencha, came from Zwirn origin). Anyway, I shall sit on the information you gave me, and try to fit it in to what I know.
Thanks for your response, because I have almost no known relatives from my father's side. I shall be in touch with you later, after I digest your information. Meir
