Henrietta, Clay County
(Early County Seat) Founded 1860, but abandoned to marauding Indians, 1863. Settlers returned in 1870 and installed a grist mill. Developers surveyed townsite in 1874; school, church, shops, and hotel were built. Post office was established and Fort Sill-Fort Richardson military telegraph line came through in 1876. First newspaper in county was founded there. Rapid growth halted when town was bypassed by Fort Worth and Denver Railroad in 1882. By then place was known as Henrietta -- the name retained when county seat was moved here. Cambridge Cemetery still exists (a mile north of historic townsite). (1971) Incise in base: Erected by Clay County Historic Survey Committee, 1971.
