Mike,
Most of my direct ancestors presumably came from around Winchester, VA around 1770's, but some of the information I have claims they came from the Pittsylvania area. Even though the information you have is some 90 years later, I am curious if any Dixon/Dixsons were enlisted in that if they were, that information might give some new leads to follow as to where they came from in the first place.
Thank you and Merry Christmas,
George C. Dixon
