He was the brother of Frances Wiener, Rose Levine and Max Schulkind, nut not related to either Annie or Herman Schulkind. He was married very briefly, no children.
Best to use Geni message and message the manager so he sees your comment.
Looks like Herman and Annie died as infants.
I had a grandfather called David W Schulkind, who had two children, Eugene and Paul (both Schulkind ). Eugene was my father. He lived in New York. Would this be a different David Schulkind?
