The town of Edgefield and Edgefield Court House are one and the same. My great grandfather's Bible records state that he was born in "Edgefield Court House, Edgefield Dist., S.C.". If you look at counties in South Carolina, you will find that most county seats have the same name as the county. This is an exception, not the rule, in Georgia for instance. In South Carolina when the early upcountry counties were created (many originally called districts) a committee would go out into the county and choose a location for the new county court house. This would usually be at some unpopulated crossroads near the middle of the county. Understandably, a town would grow up around this legal center. It would often be called [County Name] Court House. After many years, the 'Court House' part was dropped and the county seat name just became the county name.
Edgefield was once a large district (county) and was carved up into many counties. parts of Old Edgefield District are now in Aiken, McCormick, Greenwood, and Saluda counties. While once a center of political activity (no less than ten South Carolina governors and five lieutenant governors came from Edgefield), it is now a quiet, rural, upcountry area. The town of Edgefield is a great place with charm and character. There are many surviving old houses. Edgefield is about 25 miles northeast of Augusta, Georgia on US 25.
