What it means
Anglicized Irish surname Ó Cinnéidigh, 'descendant of Cinnéidigh' (a personal name meaning 'helmeted head' or 'ugly head' depending on which Old Irish root you favor).
Kennedy is the anglicization of the Irish surname Ó Cinnéidigh, 'descendant of Cinnéidigh.' The personal name comes from cenn ('head') plus either éidigh ('ugly, malformed') or a word meaning 'helmeted.' President John F. Kennedy is the obvious American anchor; the Kennedy family's place in American politics gave the surname unusual first-name potential. The flip to feminine first name happened in the 1990s, particularly in the US South. It's been in the US top 100 since 1995. Ken is the rare short.
