Caisey

Caisey is a modern variant of the Irish name Caicey, derived from the surname Casey or Ó Cathasaigh, in its Irish form. Though often used as a girl's name, Caisey works beautifully in gender-neutral contexts. It means "descendant of Cathasach," with Cathasach rooted in the Irish word for "vigilant," "watchful," or "alert." Like Casey, Caisey is an Anglicized spelling that’s still a meaningful choice for those seeking a name with Irish heritage.
