I think I am the Jim Foltz who provided the information you mentioned.
For a short time I had an online database of Foltz families. It was put up initially for personal use so my immediate family could collaborate on information.
Unfortunately, data was entered that was not researched and some of it was not accurate. I took the site offline as I realized the consequences of spreading bad information: but not until several people downloaded at least parts of it.
That being said, I am interested in my Foltz lines and here is what I think is correct in my case:
Andreas Voltzca 1586-1614 | Georg Voltz 1602/1615-1670 | Johan Jacob Voltz 1648/1671-1742 | Hans Balthus Voltz 1699-1735 | Johann Peter Foltz 1730-ca 1811 | George Foltz 1767-ca 1847 | John Balthes Foltz 1789-ca 1855 | Peter M. Foltz 1814-1874 | George Washington Foltz 1850-1932 | Earl Arthur Foltz 1881-ca 1956 | Norman Foltz 1912-1994 | Doyle Foltz 1939- | Jim Foltz 1968-
