There were 4 VOLTZ families in the Shenandoah Valley about the same time...all with similar names! Having spent years at this, I know with absolute certainty that Johann Martin VOLTZ (1721-1782) and Johann Peter VOLTZ (1730-1811) - who were 2nd cousins - came from the small towns of Boeckingen and Grossgartach, respectively, in Neckar (sort of like our county), Wuerttemberg, in what is now Germany. With equal certainty I know that Johann Georg (Hans Jurg or Joerg) VOLTZ (1729-1733) and his wife Christina Barbara JACKE b 1731 came from the towns of Griesbach and Gundershoffen, respectively, in the province of Alsace. After landing in Pennsylvania, the latter couple settled in what is now Pendleton Co., WV and was then Augusta Co., VA.
It's the Johannes VOLTZ and his wife Catherine of Rockingham (now Page) Co., VA who have always been a puzzle. There is simply no information linking them back further than 1758.
Perhaps it would help if I gave you a little something on all 4 families so you can see who belongs with whom. I never set out to do 4 genealogies when I began my husband's, but that's what I had to do in order to sort them out.
