I have a Davis line out of the Yadkin Valley area of North Carolina, Rowen County.
My earliest ancestor there was Robert Clark Davis who married Elizabeth Redwine.
It is said that Robert Clark Davis son of a David Davis and since they had a son named that name also -most likely. Also there is supposed to be a marriage connection to the Crocket family that had also settled in the Yadkin Valley. One of Robert Clark Davis's daughter who died had this mentioned in her obituary. Never found the connection.
Davis, Clark, Pollard, Smith, etc.- some of my lines - there are so many of them it is almost impossible to trace.
I think they were Welsch. They were marr'd in 1798 and came to Gibson County Indiana in 1816.
