Tracey since posting the abouve message about your g grandfather, I hope you've found answere.
I wonder if you have any assoicated names for him besides those you mentioned.? I ask because I have an Rabinowitz, with assoicated names of Silverstein, Premack and they were from Kiev I believe. and in Boston area. also by marriage there may be Pearlmutter, and Gardner.
Thank you
Barbara
