I finally have this up and running and I'm hoping to get some folks interested in joining. My ancestors came from PA and VA in the 1700's and were often listed as being Tevaults (until about 1820). I can trace my line back to Jacob and Mary Michael DeVault who came to the Monongalia County, WV area around 1795.
After seeing how surnames evolved, I believe that many of the lines could be related. I'm looking at DeVault, TeVault, Dewalt, Devaul and a few other lines. Here's more information.http://www.familytreedna.com/public/DeVault/default.aspx
Even if you don't end up related to our line you could be linked to others in the study plus you'll have your DNA on file to compare against others (not only those in the study).
