(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.

Northern English and Scottish: topographic name for someone who lived in a small hut or bothy, Middle English both(e), especially a cowman or shepherd. The word is of Scandinavian origin (compare Old Danish bōth, Old Norse būð) and was used to denote various kinds of temporary shelter, typically a cowshed or a herdsman's hut. In the British Isles the surname is still more common in northern England, where Scandinavian influence was more marked, and in Scotland, where the word was borrowed into Gaelic as both(an).
