Kacie

If you envision baby being a fizzing bundle of energy, then the American name Kacie will sum up her essence. This punchy name can be traced back to the Irish boy's name Cathasaigh, which in turn led to the name Casey. Meaning "alert" or "vigorous," it's perfect for a little girl that's always on the move. Kacie can be a diminutive of Acacia, as well as a variant of the more popular Cassie.
