Speedwell Methodist Church was founded in 1885 and took its name from Speedwell, a stagecoach stop and the first post office in the vicinity, now Millett. In 1884-85, Ogreta Brabham Dunbar and Savannah Barker Bates raised funds for a new congregation in what was then Barnwell County. In 1885, Mary Dunbar Lafitte and her husband John H. Lafitte donated a five-acre tract for the church. The first church on this site, built about 1885, was later replaced by the present church, begun in 1922 during the pastorate of Rev. W.R. Jones. It remained unfinished during the Depression but was dedicated in 1941 during the pastorate of Rev. J.A. Graham. Attendance declined in the 1960s, and regular services ended by 1970, though homecomings are still occasionally held here.
