I have Mathias as Johannes' father. Mathias born @1710 in Fredrick VA. Mathias married to Anna Grove. Although I find this confusing since I have Johannes born @1750 in Germany.
I also have found out that Johannes was a Hessian soldier. He was listed with the Kassel Fuselier Regt. von Knyphausen, and he remained in America after the Revolutionary War, then moved to Canada. I also found a Jost Groh, possibly Johannes, as a POW in Trenton during the Revolution.
Johannes is buried in the Hansler Cemetery, Pelham Township, Ontario.
My husband is a descendant of Johannes through Johannes son Michael.
