The Story of Kelly
Kelly comes from the Irish surname O Ceallaigh, meaning 'descendant of Ceallach.' The personal name Ceallach is thought to derive from the Old Irish 'ceall' (church) or a word meaning 'bright-headed' or 'warlike.' The Kellys were one of the most powerful clans in Connacht, and their name became one of the most widely distributed Irish surnames worldwide through emigration, particularly during the 19th century famine.
Kelly was a top-20 boy's name in the United States in the 1960s before rapidly transitioning to a feminine name through the 1970s. By the 1980s it had become predominantly female in American culture, though it remains in use as a male name in Ireland and among Irish-American families honoring heritage.
In Ireland, Kelly remains one of the most common surnames carrying strong Gaelic heritage. Ned Kelly, the legendary Australian outlaw, gave the name a rugged rebellious edge in antipodean culture that endures today.
