I've been working on this line for a few days for Jay Rosenberg. He is the son of Robert Adolph Rosenberg and Anna (Chana) Adin. His grandparents are Joseph Rosenberg and Bessie Weinstein.
I would like to chat with you folks about sharing sources. I have found some records which I think you may want. You may also be able to help me. At the moment, Jay is particularly focused on learning more about his Weinstein side but I'm building his tree to include both lines.
I can be reached by email: family @ digging4roots.com.
