The second element of this is Old English cumb ‘short valley’, ‘combe’ (see Coombe); the first is probably either an Old English personal name, Morta (see Mort) or mort ‘young salmon or similar fish’. The surname is not from Morecambe in Lancashire, which is an 18th-century coinage, based on identification of Morecambe Bay with Morikambē ‘great gulf’ in the work of the ancient Greek geographer Ptolemy.

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.
