Are you sure that two, (if not all three), of the Abraham Silvermans are not the same person? I discovered a grand-uncle, and his family, living in Brooklyn in the 1930 U.S. Census - taken in early June. Later that same month, in the same 1930 Census,  the family was living in upstate New York. Apparently they had relocated, and since the two recordings were taken on different dates, they were listed twice.  Families do move around for various reasons.
