My Davis Line or Lines?

I am seeking that Davis family which links my two ggrandparents. My paternal grandparents, John Aaron Davis and Lee Ann Brunson, were supposedly related. John's grandfather was Aaron T. Davis (1826 GA - 1894 AL), s/o unknown. Lee Ann's great grandfather was Aaron Davis (bef 1774 NC - aft 1823 GA), s/o Benjamin Davis. I know that Aaron and Priscilla McElroy Davis had 3 children. Lee Ann Brunson was a direct descendent of their daughter, Mary Allis Davis (Rutherford). The other two children (according to 1800 census) were male. Questions: Could one of these boys be the father of Aaron T. Davis? Who were the parents of Benjamin Davis?
