The Village of Adelphi was founded in 1804.  It is located in the northeast corner of Colerain Township and Ross County, and is the principal town in Colerain township.  The town was surveyed and laid out by Gen. Nathaniel Massie for Reuben and Henry Abrams in 1804. Adelphi was incorporated by act of the State Legislature in 1838. The first religious organization in Adelphi was that of the Lutheran church in 1810.  A lodge of Odd-Fellows (Masons) was organized in July, 1848.  The first newspaper, under the title of the “Adelphi Border News,” was established January 1, 1879, by D. F. Shriner.  The first cemetery in Colerain township was established in connection with the Lutheran church, on Concord Street, in Adelphi.  Interments were made in Adelphi Cemetery as early as 1807.  There are also two old small cemeteries, Old Methodist and Belleview-Strouse, located on Market St., but these have been superseded by a larger public burial place located outside of the village, Green Summit Cemetery.
