William Harper

(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, Scottish, and Irish: occupational name for a player on the harp, from an agent derivative of Middle English, Middle Dutch harp ‘harp’. The harper was one of the most important figures of a medieval baronial hall, especially in Scotland and northern England, and the office of harper was sometimes hereditary. The Scottish surname is probably an Anglicized form of Gaelic Mac Chruiteir ‘son of the harper’ (from Gaelic cruit ‘harp’, ‘stringed instrument’). This surname has long been present in Ireland.
