David: I am Mel Bowman my 5xgfather is Johannes Bauman from Switzerland.He settled in what is now Lebanon County in PA.
There is a Johannes Bauman and Nicolas Ellenberger on the Robert and Alice to Philadelphia in 1739. Sally Roberts a professional genealogist has done considerable research on my Bowman family. She suggests it was our Johannes on that ship.
I have one marriage with Ellenbergers in the late 1700s.
Magdalena, dau of Jacob Ellenberger married John Bowman son of Abraham, grand son of Johannes. They had 10 children
I have been searching a long time for Johannes birth palce and date in Switzerland.
Do you have the birth place of Nicolas Ellengberger?
