Hello,
My great grandfather is Joseph O'Brien, he changed his name from Joseph Neftelberger. He was raised by Pat O'Brien. William and Joseph were the only children of Joseph Neftelberger that changed their name. Most of the children have shorten their name down to Neftelberg or Neftleberg. You can locate family on Long Island today and family in Queens. I've seen Nathan and Bertha's Information online but thought that was 1 generation prior to the "abandonment of Joseph's children to be raised by O'Briens". I would like to find out why these children where raised by non-family and why the family abandoned these children because Joseph married outside of the jewish faith. Do you know any history..email me
