I'm looking beyond what is posted on Carol Yarbrough's site and make contact with anyone working on these lines. Including Rentfro, Griffith, Peak and Rippitoe that married into these lines. Several of these families migrate from southern part of VA to counties in East TN.
I will be going to Salt Lake City in a couple of months and am looking for new clues to follow in Virginia and Tennessee. Gladly share what I find on that trip.
