I have Willis Hayes and Charlotte Howard b. abt. 1792 in Edgefield Co. SC, m. abt. 1812/13 in Anderson County and I think most children b. there, they were in Anderson at least through the 1840 census but by 1850 were in Talladega Co. AL. Their children 1) Jared Howard 2) Harmon Howard 3)George Pulaski "Hosea" 4) C. Rebecca 5) Seth W. 6) William 7) Adrah 8) Hiram.
I have extensive info on the Howard family and there is a book by Marilee Cory that follows the Howard line. I'm not sure about Willis Hayes' parents but lots of "clues" on Hays in Anderson Co.
I'd like to hear from anyone who is researching Hays in SC prior to 1790.
