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, Maryland
Manchester was the home of one of the first colleges in Carroll County when, in 1858, Irving College, named after poet Washington Irving, was established by Dr. Ferdinand Dieffenbach. During the Civil War the success of the school was greatly hampered by the death of Dr. Dieffenbach and the low number of young men returning from the front lines. The school changed its name to Irving Institute in 1886 and finally ceased operation by 1893.
