William Knight

(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: status name from Middle English knyghte ‘knight’, Old English cniht ‘boy’, ‘youth’, ‘serving lad’. This word was used as a personal name before the Norman Conquest, and the surname may in part reflect a survival of this. It is also possible that in a few cases it represents a survival of the Old English sense into Middle English, as an occupational name for a domestic servant. In most cases, however, it clearly comes from the more exalted sense that the word achieved in the Middle Ages. In the feudal system introduced by the Normans the word was applied at first to a tenant bound to serve his lord as a mounted soldier. Hence it came to denote a man of some substance, since maintaining horses and armor was an expensive business. As feudal obligations became increasingly converted to monetary payments, the term lost its precise significance and came to denote an honorable estate conferred by the king on men of noble birth who had served him well. Knights in this last sense normally belonged to ancient noble families with distinguished family names of their own, so that the surname is more likely to have been applied to a servant in a knightly house or to someone who had played the part of a knight in a pageant or won the title in some contest of skill.
