William Dodd

(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: from the Middle English personal name Dodde, Dudde, Old English Dodda, Dudda, which remained in fairly widespread and frequent use in England until the 14th century. It seems to have been originally a byname, but the meaning is not clear; it may come from a Germanic root used to describe something round and lumpish—hence a short, plump man.
