1700 can't be the year Johann Stumpf (AKA John Stump) he was born, as well as the year he and his wife Mary Bakerin emigrated from Prussia to Maryland in America. The sources quoted are contradictory, yet this has not been resolved before posting on Wikitree. Need help in researching what is his actual year of birth, and what is actual year of emigration. Please help clarify the confusion. Thanks!
