English (chiefly West Midlands)
English (chiefly West Midlands) : (of Norman origin): habitational or regional name from Old French mansel ‘inhabitant of Le Mans or the surrounding area of Maine’. The place was originally named in Latin (ad) Ceromannos, from the name of the Gaulish tribe living there, the Ceromanni. The name was reduced to Celmans and then became Le Mans as a result of the mistaken identification of the first syllable with the Old French demonstrative adjective.English (chiefly West Midlands) : status name for a particular type of feudal tenant, Anglo-Norman French mansel, one who occupied a manse (Late Latin mansa ‘dwelling’), a measure of land sufficient to support one family.English (chiefly West Midlands) : some early examples, such as Thomas filius Manselli (Northumbria 1256), point to derivation from a personal name, perhaps the Germanic derivative of Mann 2 Latinized as Manzellinus.

English : topographic name for someone living on (and farming) a hide of land, Old English hī(gi)d. This was a variable measure of land, differing from place to place and time to time, and seems from the etymology to have been originally fixed as the amount necessary to support one (extended) family (Old English hīgan, hīwan ‘household’). In some cases the surname is habitational, from any of the many minor places named with this word, as for example Hyde in Greater Manchester, Bedfordshire, and Hampshire.English : variant of Ide, with inorganic initial H-.
