Founded in 1870s. Among first settlers were the families of Andrew, Mark, and Polk Oliver; Stephen M. Lewis; William Faver; Matt Senterfitt; Asa J. Howard. The only building (a two-story frame structure housing Cumberland Presbyterian Church and local school) was built by citizens in 1877. Andrew and Mark Oliver gave land for building and cemetery. Community got its name because people worked in harmony on construction. Second story was removed in 1911 and brick veneer was added in 1960. Cemetery group meets yearly although community is inactive.
