More information on Neftelberger name. Joseph Neftelberger married ? Collins. Joseph Neftelberger was a Banjo Maker - Instrument. New York City area. Married out side of his faith - Not of Jewish faith, she passed away and the children were ofphans. Joseph, Raymond, Charlie, Walter and William (there were a couple of girls) where raised by Lillian Moll O'Brien. Joseph left the children with Lillian Moll O'Brien to return to his family the Neftelberger's. I am very interested in bridging the gap and can not locate any Neftelberger's here in the United States. Any information or leads will be helpful.
