Look for Michael Mattox (or as Maddox) as possibly father of Sallie. He is the only one of that surname to receive a Commonwealth land grant in Franklin County. His grant was for land on what was called Muddy fork of "Chesnut Creek" [not "Chestnut Creek"] It was on the southern end of Chestnut Mountain, in southwestern Franklin County, and near to the line with Henry County. One Samuel Dent was a near neighbor of Mattox'. Good bet he is her father. Good hunting !
