In my line there is a Johannes Balthaser Durr that changed his name, or his dad, Gasper, changed it to John Baltzer Tarr.I believe that the change from Durr to Tarr or even Darr was a result of the names being "Americanized."
Gasper and family camve from Germany in the 1700's, probably around 1750's.
Here is all I have so far, any more info anyone can provide would be appreciated:
