My great-grandfather was born Bernhard Flocker in Rietvas/Retovo, Lithuania (abt 1864) before emigrating to New York in 1888 and then Boston a year later. He went to medical school in Vienna and practiced in the Boston area at the College of Physicians and Surgeons of Boston. I'm trying to track down his family, a father Maurice, mother Reine (I got the names from his marriage record) and possibly a brother who may have move to South Africa, name unknown. I would appreciate any assistance in helping me track them down.
He changed his name to Frank Flocker Bernard. Thanks in advance.
