On Saturday, April 2, 1831, a church was organized at the Harmony Meeting House. Thomas Morgan served as the first pastor. A few years later, the first Baptist association was organized by Rev. John Gilliland. Harmony was one of the first five members in the association. The adjoining cemetery, Old Harmony Cemetery, has been declared a historic landmark. This cemetery has black and white slaves buried in it, Native Americans, single and double interment, and most of the tombstones have poems and writings on them. They say one man is buried crosswise because he lived crosswise with the world.
