I also found information that he was born in 1741 (which I have left on the tree at this time)as well as 1760 with his brother, Conrad, born in 1759. I allow people to view my information, so I'll add your name to the list. It's a living document, and not posted to world tree as I find things that need to be modified on occasion as I continue the work.

I'm delighted to exchange information! My email is highdesertrose@hotmail.com if you ever want to contact me there.

Where are you located? My grandmother, Eunice Olive Bolton, was from Iowa. Her father was George Albert Bolton. She was the first daughter to leave home and get an education and embarked on a nursing career which she maintained until she was forced to retire at 72.
