Meaning & History
Williams is an English patronymic surname meaning "son of William." It originated as a variant of William with the addition of a genitival or post-medieval excrescent -s, following the common pattern of forming surnames by adding a possessive or plural suffix to the father's given name. The surname is especially frequent in Wales and England, and in Ireland it sometimes represents an anglicized form of the Irish patronymic Mac Uilliam (McWilliam).
William itself derives from the Germanic name Willehelm, composed of the elements willo ("will, desire") and helm ("helmet, protection"), meaning roughly "will helmet." Introduced to England by the Normans after the Conquest of 1066 – including William the Conqueror – the given name rapidly became a staple of English nomenclature.
The longevity and ubiquity of William have generated a vast array of patronymic surnames beyond Williams itself: Wilson, Williamson, Willis, and Wilcox all stem from the same root, as do foreign equivalents: Dutch Willems, Willemse, and Willemsen; French Guillaume and Guillot; and Gilliam or Worrell.
The surname Williams has also been carried to toponyms: at least two places in the United States bear the name, notably the city of Williams in California and the city of Williams in Arizona, the latter named for frontiersman "Old Bill" Williams.
