William Smith

(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: occupational name for a worker in metal, from Middle English smith (Old English smið, probably a derivative of smītan ‘to strike, hammer’). Metalworking was one of the earliest occupations for which specialist skills were required, and its importance ensured that this term and its equivalents were perhaps the most widespread of all occupational surnames in Europe. Medieval smiths were important not only in making horseshoes, plowshares, and other domestic articles, but above all for their skill in forging swords, other weapons, and armor. This is the most frequent of all American surnames; it has also absorbed, by assimilation and translation, cognates and equivalents from many other languages (for forms, see Hanks and Hodges 1988).
