I am researching the same Wynne family that you are. However, I am researching Robert Wynne who died in 1811 in Warren Co., Ga.As best I can determine Robert was a brother to your Joshua IV.I have had difficulty in determining if Thomas G. Wynne born abt 1797 and died Jan 20 1853 in Warren Co., Ga is the father of the next Wynne in the line I am working on....namely Henry A. Wynne.Henry is in the household of Thomas and Cynthia Wynne in Warren Co in 1850. In 1860 he is married. Henry remains in Warren Co until after the 1880 census when he moves to Dallas, Tx. He died in Dallas in 1888.Do you have any documentation that might help me???
