Following the Civil War, Thomas Jefferson Mayo moved to Paintsville to fulfill a role as a gifted and talented teacher. He fathered John C. C. Mayo, an important figure in the development of eastern Kentucky. The county citizenry is divided on their loyalty to his memory. Some would say he was a benefactor who assisted in the development of Paintsville, and as a result, Johnson County. That he helped develop banks, churches, streets, public utilities and railroad transportation. Others would say he was directly responsible for the huge influence coal companies had over the county's vast coal resources and the reason the region remains so economically depressed to this day.
