William Pastor

(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.

1. English, Portuguese, Galician, Spanish, Catalan, and French: occupational name for a shepherd, Anglo-Norman French pastre (oblique case pastour), Portuguese, Galician, Spanish, Catalan, pastor ‘shepherd’, from Latin pastor, an agent derivative of pascere ‘to graze’. The religious sense of a spiritual leader was rare in the Middle Ages, and insofar as it occurs at all it seems always to be a conscious metaphor; it is unlikely, therefore, that this sense lies behind any examples of the surname.
