Four Georgia governors have come from Hancock County: Nathaniel Harris, James McDonald, William Northen, and William Rabun.
The Oconee River makes up much of the western border of the county. Located on its banks are the Shoulderbone Indian Mounds, which date back to approximately the fourteenth and fifteenth century.
