My Weingarths came from Pfalz, Bavaria in the 1850s and settled in Eastern Ohio - Tuscarawas Co, to be exact. Many German immigrants congregated there because the terrain reminded them of their home country. The name was Weingarth in Germany and remained Weingarth in America...however, some census takers, county clerks, etc. managed some very creative spellings of it!!
I would be happy to exchange information with other researchers on these Ohio Weingarths.
