My Brunner ancestors are originally from Switzerland, specifically from Bassersdorf, Canton Zurich. My immigrant ancestor, Felix (Phillip) Brunner, came to Pennsylvania sometime before 1767, where he died in Milford Township, Bucks Co. in January 1818. Would love to share more info on this forum, but unfortunately I haven't yet figured out how.
My third great grandfather John Brunner came to the US with his brother from Switzerland, and ended up in Switzerland Township, Monroe County, Ohio.
The Brunners married other Swiss immegrents for a couple generations until my grandfather married my grandmother from Belmont County, Ohio.
