Did your John marry Eleanor Key?I am also descended from Cornelius K. Donahoo who married Elizabeth ? about 1788 in NC.They had Susanna, James, Cornelius K., Nancy, Rachel, John H., Barnette William, Eleanor, and Maryanne.
Cornelius K. Donahoo died Sept. 1859 in Cobb Co. GA where his wife had died in 1842.
Son Cornelius Kirkley Donahoo(born 1795 Laurens Co., SC) married Nancy Parks Dec. 29, 1822 in Franklin Co., GA.They moved to Pickens Co.,AL where they raised 7 children.
Would love to know more about John. Appreciate your help.
