I was researching today at the Courthouse in Morgantown WV and found a record in one of the court order books for Abraham and Isaac Covault. It was from the 1800's and since I have an Abraham and Issac in my line from there I figured they were mine and I was going to go back to that record and forgot. I them look up the Covault name and see they are in surrounding states and even parts of WV but not that part. So either it was a mistake (I'm used to seeing Tewalt/Tevault/ DeVault/Devolt) but never Covault. I'll have to check that record when I go back next month.
I do have a YDNA Surname project though and since nothing surprises me anymore (I found I'm related to both a Tevault line and a Dewalt line) I'll add this link in case anyone is interested in joining. We have many surnames in the project including the three above plus Dewald, Devall, Duvall, and a few more. The link says "DeVault" but that's only because I couldn't list every variation - we want more surnames to join.
