Wendell, I hope this might help some to forward your search. The first name Doctor is not because he was a doctor but because somewhere in his lineage is the surame Doctor from VA. They were in the Fredericksburg area near Travillion. The Tankersley's were also from there. And a road where this family originated is named Doctor road. I have 2 other surnames in that time period where the child was named Doctor. And also Hiram/Hirum which also is a surname. The practice of giving a child a first name which was the mothers maiden name or even one of the grandmothers was practiced during this time period. I would suggest looking at Virginia for the ancestors of these Tuckers.And from the age of your Doctor I would doubt he could have been one. This has confused many a researcher. Pat
