Encyclopedia of Alabama: St. Clair County
St. Clair County was created from portions of Shelby County by the Alabama Territorial General Assembly on November 20, 1818. Two years later, part of St. Clair County was used to create Jefferson County. Then, in 1836, a portion of St. Clair was divided to establish Cherokee and DeKalb counties. After the Civil War, a northeast section of the county was used to create Etowah County, resulting in St. Clair’s present boundaries. The county was named in honor of General Arthur St. Clair who traveled to America from Scotland as an ensign in the British Navy. St. Clair settled in Pennsylvania and became a general in the Continental Army during the American Revolution and president of the Continental Congress. Most of St. Clair County’s early settlers came from Tennessee, Virginia, and the Carolinas. Some of the county’s earliest settlements and towns were Ashville, Odenville, Riverside, and Springville.
