Regarding John George, 1765,I too have a flock of Zimmermans in Berks County. I am stuck at Jacob b. 1765, d. 1843 in Hempfield tp. He had nine children and his son Benjamine is my line. I can't help but think that we have a common ancestor between John George and Jacob. If I run into him I will let you know. If anyone else can help it would be much appreciated. Richard Lisle
