The 1880 census found 237 people residing on homesteads strung along more than six miles (10 km) of Cottonwood Creek. In that year two townsites were surveyed, one known as Upper Castle Dale and the other as Lower Castle Dale. In 1882 Upper Castle Dale took the name Orangeville in honor of Orange Seely, even though he resided in the lower town. The two communities, only three miles apart, have had closely related histories, but Castle Dale has been home to the main public institutions.

A couple of DUP Markers in Orangeville I have posted about are:
