Kaci

Kaci is a modern spelling in the Casey family, which developed from an Irish surname. Casey comes from Ó Cathasaigh, meaning descendant of Cathasach, a personal name associated with being watchful or vigilant. The meaning therefore reaches the given name through a family name rather than through the individual letters of Kaci.

Casey has been used as a given name for both boys and girls, and spellings such as Kaci and Kacey show how that surname name has taken on new written forms. Kaci keeps the familiar two-syllable shape while using an i ending. For a family honoring a Casey, the shared history is more significant than the different choice of letters.
