No known connection to any Stahlman immigrants especially after 1800. Out John Sr. bca. 1758 probably in U.S. born of immigrant parents. This Johnmay have been connected to other Stahlman's in eastern Pa. in mid to late 1700's.To link the families you would probably have to find yours and ours in Germany.We can't find our immigrant ancestor.Over 75% of Stahlman family in America are descended from our John bca. 1758.Good luck.
