Settlement began in the area as early as 1820, and by 1826 there were enough residents for the incorporation of the two oldest towns, Somerville and LaGrange. In both towns restored antebellum homes symbolize the wealth and culture of the plantation period. The entire town of LaGrange, named for Lafayette's ancestral home, is listed in the National Register of Historic Places. Today there are nine incorporated towns in the county: Braden, Gallaway, LaGrange, Moscow, Oakland, Piperton, Rossville, Somerville, and Williston.
