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").
Mans (surname)
Until the twentieth century this surname in England was virtually confined to the Welsh Marcher counties and adjacent districts, reflecting the settlement there by King Henry II of his feudal followers who had accompanied him to England from [Le] Mans and other parts of Maine in France in 1154, a number of whom appear in medieval records under the name de Mans or del Mans(French and Latin respectively for 'of Mans' as Le Mans was then known, sometimes with the further description 'Cenomanus' making the city these men came from crystal clear. The name was sometimes spelled by Anglo-Norman clerks Mauns and de Mauns and later also Manns.
