I do not know any more. He was my father's uncle but he never met him. He is on the 1930 US census with his mother, some unmarried sistes and brother Anthony, his (Benjamin's) father is on the 1930 Mexican census. My father wrote him once in the 1950s in Mexico and he got a response but heard nothing further. We know nothing of any marriages or any return to New York. In fact, all evidence in my dad's memory (80 and a judge and very sharp) is that Benjamin was not in the US through and into the 1950s. I am sorry I know so little.
