(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: occupational name for an archer, Middle English bow(e)man, bouman (from Old English boga ‘bow’ + mann ‘man’). This word was distinguished from Bowyer, which denoted a maker or seller of the articles. It is possible that in some cases the surname referred originally to someone who untangled wool with a bow. This process, which originated in Italy, became quite common in England in the 13th century. The vibrating string of a bow was worked into a pile of tangled wool, where its rapid vibrations separated the fibers, while still leaving them sufficiently entwined to produce a fine, soft yarn when spun.
Americanized form of German Baumann (see Bauer) or the Dutch cognate Bouman.
