1866 map by J.H. Colton showing the eastern half of the Republic of Texas (Texas joined the United States in 1845, seceded in 1861 and re-joined in 1870). Zoom in shows Denton County, including the cities of Denton and two towns that no longer exist: Alton and Lexington. The Elm Fork of the Trinity River (no longer labeled as the Trinidad River in order to sever ties to Mexico) is also labeled on this map.
