The family knows very little. They think he was born in Appleton and probably changed his name in his twenties and when he dad found out he was very angry and they became estranged. I think the guy went to college so I imagine my friend might do well to look through a year book or two around the 1938 year or so for an Appleton high school. I would imagine that he was not an only child because as far as the family knows there was never any contact between him and his kin even after the children were born. The thought maybe the name was Rosenbaum or Rosenblatt or something like that. Any clues about who this might be?
