I found a William Keethley age 75 born in SC and his wife, Susannah age 76 born in NC on the 1850 Pike County Census.
They lived next to a family Henry Keethley age 35 born in Tenn. and his wife Nancy age 32 born in Va.All there children were born in Kentucky.They were Sarah A. 14, James A 13, Oliver 10, Christopher 8, William T 6, John F 5, Margaret J 3, and Thomas 11/12.
I know that the above Henry is Henry Sevier Keathley and his wife Nancy Trout, dau. of Christian and Elizabeth Geerhart/Gearhart.
In the 1860 Census of District 1 Pike Co. Ohio, Susannah was listed as living with Henry Sevier.
Does anyone know if William and Susannah are the parents of Henry Sevier?
