Historical notes

First court in Franklin County
In 1785, the Yazoo land fraud caused the state of Georgia to surrender its claim on what is now Alabama and Mississippi. South Carolina took advantage of the situation to move the boundary with Georgia from the main branch of the Keowee River to the Tugaloo branch, absorbing some Franklin County territory. Like other Georgia counties at the time, Franklin County had to decide which land claims were legitimate and which were fraudulent. The first county court was held at the home of Warren Philpot on Gumlog Creek. George Walton, a signer of the Declaration of Independence, was the court's chief justice. The assistant justices were Jesse Walton, Benjamin Cleveland, Larkin Cleveland, and John Gorham.
