Syd,
I happen to be somewhat of an expert on the subject of Sing-Sing. I'm actually writing a book about Jewish inmates at the prison......
The most valuable sources of information about Sing-Sing inmates are:
- the admissions registers which are held by the New York State Archives in Albany. I have photographed admissions records (1880-1950) for all inmates who claimed to be Jewish. So, if your grandfather was Jewish, you're REALLY in luck.
- Federal and State Censuses which, surprise, I also have in my possession.
If, by chance, you're grandfather was Jewish, I'd love to include his story in the book that I'm writing.
