Clifton was founded in the winter of 1852–1853, when the families of Frank Kell, Joseph A. Kemp, Samuel and Monroe Locker, and T. A. McSpadden settled in the vicinity. The town was named Cliff Town after the surrounding limestone cliffs. Over the years the name was altered to Clifton. The site was originally on the banks of Clear Branch. The Masonic lodge hall and a log schoolhouse were the first public buildings. The post office was established in 1859. The First Presbyterian Church of Clifton was organized in 1861 and is the county's oldest church in continuous service. The Baptists built the first church building in Clifton in 1884–85. After the Civil War, Joel Martin Stinnett (1806-1875), the grandfather of Joseph Kemp, built a flour mill powered by the Bosque River. In 1868, this mill was replaced by a limestone mill, which was converted to the electric power plant that provided the first electricity for Clifton homes and businesses. A three-story school known as Rock School was built about 1870 and served the community for more than twenty years. In 1893, a new building was constructed on property donated to the Clifton school system.
