What Does the Name Kelly Mean?

Kelly is an Irish name derived from the surname Ó Ceallaigh, which means 'descendant of Ceallach.' The surname is a patronymic formed with Ó, 'descendant of,' and the personal name Ceallach. The meaning of that earlier name is not securely known. One explanation connects it with Old Irish cellach, 'strife' or 'contention'; another links it with ceann, 'head,' in the sense 'bright-headed.' The familiar glosses 'warrior' and 'bright-headed' are interpretations of Ceallach, not separate origins of Kelly. The surname's literal genealogical meaning is 'descendant of Ceallach.'

Kelly Name History & Origins

The personal name behind Kelly appears in early Irish records as Cellach, later spelled Ceallach. It was borne by early Irish saints, including Saint Ceallach of Killala, and by kings in several small Irish kingdoms. From this name, Irish families formed the patronymic surname Ó Ceallaigh, meaning 'descendant of Ceallach.' In English records the Ó was often dropped, giving O'Kelly and Kelly; Kelley is a common variant spelling. Because the personal name was used in different parts of Ireland, the surname arose in more than one family.

Kelly was also used as a given name in Ireland as an anglicized form of Ceallach. In the English-speaking world, it became a transferred use of the surname. It was used as a male given name before becoming established as a female given name in the United States in the 20th century, while continuing in use for men as well.
