Manchester
The name Manchester originates from the Latin name "Mamucium" or its variant "Mancunium" and the citizens are still referred to as Mancunians (). These are generally thought to represent a Latinisation of an original Brittonic name, either from "mamm-" ("breast", in reference to a "breast-like hill") or from "mamma" ("mother", in reference to a local river goddess). Both meanings are preserved in Insular Celtic languages, such as "mam" meaning "breast" in Irish and "mother" in Welsh. The suffix -chester is a survival of Old English "ceaster" and from that "castra" in latin for camp or settlement ("fort; fortified town").
Manchester, Michigan
Originally from upstate New York, John Gilbert resettled to Ypsilanti, Michigan, in 1831. In 1832, he decided to turn his attention to the extensive land tracts he held in the area. He commissioned the construction of a grist mill along the Raisin River upon the land he had purchased in 1826. The original plat of the village of Manchester was prepared by surveyor Hiram Burnham and dated 1833, but was not formally filed until March 25, 1835. The location was chosen to take advantage of water power from the river and named after Manchester, New York.
