History of Manchester
According to Oxford University Press, Manchester derived its name from Mamucium, the Roman name for the 1st century-settlement and fort. Mamucium itself is a Latinised form of the Celtic meaning "breast-shaped hill".
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.
