I descend from Barbara Tinney, Rebecca's sister, who married Jacob Born Robertson Peters.In addition to the Tinney's, I have a great deal of info on the Doss line.This was given to me almost 25 years ago by Nellie Doss McCoy, of Lilburn, GA, with whom I met and corresponded for some time.She was the family historian and was quite thorough with her research. I lost contact and am not sure that she is still living. A book compiled by the Gwinnett Co. Historical Society called "Gwinnett County Families 1818-1968" includes her Doss line starting with George Doss, grandfather of James Jefferson Doss, and includes the next 3 generations.While I normally am very cautious about accepting data from secondary sources, I found Nellie's research to be well documented and our letters and visits confirmed it. I believe she was a descendant of Isaac Terrell Doss, Rebecca's brother. Susannah Ellender Doss married William Jefferson Bradberry. Which of theirchildren are you descended from?
