I have been trying to trace Johann Georg Bechtolsheimer (Becklehymer), and I think I have hit the mother of all brick walls. I would like some input from fellow family members.
It occurred to me that since the Amwell Brethren all changed their names, that Bechtolsheimer was perhaps an alias, as there was no mention of him on any ships from 1708-1733. It occurred to me that "Bechtolsheimer" could very well just mean "a person from Bechtolsheim". Sure enough, there is indeed a town in Germany called Bechtolsheim, and it was a haven for Mennonite Christians.
So now here's the trick: if we could look at the records from 1702-1712 in Bechtolsheim, we could possibly discover which Johann Georg was born there, yet did not die there. At that point, perhaps we could cross reference passenger lists?
So ... is anyone planning a trip to Germany any time soon? :)
