Hi - I just returned to this forum for the first time in a few years and saw your posting. I believe that Isadore Fagin was the sister of my great-grandmother Rose Fagin! Their parents were Hyman and Sarah Fagin. I have no information about Isadore's children other than the names Archie, Herman, and Morris, a list that seems to not becomplete. Anything else you can tell me would be wonderful! I would be happy to email or fax you my GenoPro tree, just tell me how to get in touch.
