My great grandfather, Morris, came to America from Bialystok with his sister, Chaya in the mid 1930s. Morris had between 3 and 5 other sisters in Bialystok at the time of the Holocaust. His parents, sisters, nieces, nephews, everyone he was related to except Chaya was killed, most in Auschwitz. His father might have been named Samuel. That is all the information I have on his perished family. Any help regarding the Meyerson family or anyone related to would be greatly appreciated, not just for my research but my family
