After re-reading your post, it occurs to me it's possible we have a match after all. I can't explain Abraham having a son Anton, though - I haven't found a record of the name, but Jean could possibly be the same Jean, or John. The locations could be possible. Don't know about Pierre, but John (or Jean) had a son Peter (French spelling Pierre), and they would have settled in the Berks County, PA area, near Philadelphia. Peter also had a son, Peter.
