Kayce

Girl / Boy name · 19 babies recorded · 1974–2025

Kayce: 19 babies born in Scotland since 1974, given to both boys and girls, peaking at 7 births in 2025.

Derived from the modern American English respelling of the Gaelic name Casey or the Irish surname Ó Cathasaigh, Kayce means “vigilant” or “watchful,” rooted in the Old Irish element *cath* for “battle.” While less common in Scotland than its traditional counterpart, the name gained mild traction as a unisex option, particularly in the late 20th century. Famous bearers are few, though it shares etymological kinship with the Irish actor Casey Affleck, whose surname honours the same vigilant origins. No major places bear the name directly, but the phonetic resemblance to “K.C.” has led occasional associations with Kansas City. Kayce remains a stylised, contemporary choice, favoured by parents seeking a softer, modern twist on a classic Celtic surname.
