I have a John Alexander b. 1794.That is all that I have for him.However, his parents were Wm. M. (or F.) & Elizabeth (Sturgeon) Alexander, Sr.Wm. was born in PA and died in Maury Co., TN, or Cornersville, Giles Co., TN. I have 13 children for them.Children born from 1788-1907.Could this be the John you seek?
If so, please give me some data on him, and I will give you what I have on his ancestors.
