The Story of Kaci
Kaci is a variant spelling of Casey, which derives from the Irish surname Cathasaigh or Ó Cathasaigh, meaning watchful, vigilant, or brave in battle.

Casey and its variants peaked in popularity in the United States during the 1980s and early 1990s. The name was championed by characters in popular media and benefited from the trend of gender-neutral names. Kaci with a K gained particular traction as a feminine spelling in the 2000s.
