(male) Probably the most successful of all the Old French names of Germanic origin that were introduced to England by the Normans. It is derived from Germanic wil ‘will, desire’ + helm ‘helmet, protection’. The fact that it was borne by the Conqueror himself does not seem to have inhibited its favour with the ‘conquered’ population: in the first century after the Conquest it was the commonest male name of all, and not only among the Normans. In the later Middle Ages it was overtaken by John, but continued to run second to that name until the 20th century, when the picture became more fragmented.

English and Scottish: status name or occupational name from Middle English, Old French maresc(h)al ‘marshal’. The term is of Germanic origin (compare Old High German marah ‘horse’, ‘mare’ + scalc ‘servant’). Originally it denoted a man who looked after horses, but by the heyday of medieval surname formation it denoted on the one hand one of the most important servants in a great household (in the royal household a high official of state, one with military responsibilities), and on the other a humble shoeing smith or farrier. It was also an occupational name for a medieval court officer responsible for the custody of prisoners. An even wider range of meanings is found in some other languages: compare for example Polish Marszałek (see Marszalek). The surname is also borne by Jews, presumably as an Americanized form of one or more likesounding Jewish surnames.
