my granfather was burton rubak, acccording to his birth and death certs, born to john rubak and myrtle raymond nov 26, 1913, though we always knew him as raymond burton ruback or sometimes rubeck. all his descendants go by rubeck. story is he changed name from rubeck to ruback to not sound polish but not sure why or if legally done.he was born in lackawanna county of erie new york near buffalo and had sister helen. any chance he somehow links to your family?
