Hi there, David. Robert (Rachmel) is my grandfather on my father's side, and I can add a little more info to his profile if we merge our trees (however that works... I'm new to geni and I don't have a pro account). For now I can mention that the date of his death is off by a year: he died in June 1969.
Thanks so much for everything you've done in compiling all this family history! It's an incredible gift for all of us.
