Kennedy
Kennedy Name Meaning, Origin & Popularity
KEN-ih-dee
Meaning of Kennedy: Kennedy derives from the Old Irish surname Cinnéide (O’Kennedy in its clan form), composed of ceann (head) and eide (armored, helmet) or possibly éide (ugly, misshapen)—giving either helmet-headed or misshapen head as the working meaning.
The surname belonged to the Dál gCais clan of County Clare and County Tipperary in Ireland, one of the most powerful medieval Irish dynasties alongside the O’Briens.
The Kennedy family of Massachusetts—particularly President John F. Kennedy (1917–1963) and his family—gave the surname its American cultural identity as a symbol of Irish-American political ambition and tragedy.
What Does Kennedy Mean? Origin & Etymology
According to SSA records, Kennedy appeared as a girls’ given name sporadically before 1990 but gained significant traction only in the late 1990s alongside other presidential surname names given to girls: Madison, Taylor, Reagan.
According to SSA records, Kennedy entered the US girls’ top 200 in 1999 and the top 100 in 2010. It peaked at rank 57 in 2015 with over 4,200 births. As of 2024, it ranks #89 with 3,367 registered births.
The name follows the same surname-to-girls’-name trajectory as Madison, Reagan, and Morgan—though Kennedy’s specifically Irish and presidential associations give it a distinct cultural flavor.
The political Kennedy dynasty—John F. Kennedy, Robert F. Kennedy, Ted Kennedy, and a third generation including Caroline Kennedy (US Ambassador to Australia)—keeps the name in continuous public visibility.
Notably, Kennedy is the only presidential surname that is also a widely used girls’ first name today, whereas Jefferson, Lincoln, and Roosevelt have not made similar crossovers.
