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, Connecticut
Manchester was settled by colonists around 1672 as a farming community, although at the time it was known just as Orford Parish (the name that can be found on the memorial to the Revolutionary soldiers from the town). The many rivers and brooks provided power for paper, lumber and textile industries, and the town quickly evolved into an industrial center. The town of Hartford once included the land now occupied by the towns of Manchester, East Hartford, and West Hartford. In 1783, East Hartford became a separate town, which included Manchester in its city limits until 1823.
