I have no idea if Morris had a brother or not. I also do not think they ever changed thier name. My g-grandfather was Morris, he was a milman. His wife was Rebecca or Beckie and they had at least 4 children. May, George, Arthur and Tess, my grandmother. I am told they had another child Martin but I can't find any record of his birth. I do know that by 1930 Morris had passed. Any of this help?
