History & Origin

Kayley has a double pedigree. As an Irish surname, Kealy or Keeley descends from Γ“ Caollaidhe, rooted in caol, 'slender'; as a modern given name, it usually represents a blend of Kay β€” itself short for Katherine β€” with the popular -ley ending, part of the same family as Hayley and Bailey. Some parents also connect it to the Irish cΓ©ilΓ­, the festive social dance.

The Kaylee sound exploded in late twentieth-century America in a dizzying array of spellings β€” Kaylee, Kayleigh, Kaylie, Kailey, Kayley β€” together making it one of the defining girl-name sounds of its era. The -ley spelling is among the less common, giving a slightly British finish to a thoroughly modern favorite.

Did you know? The animated film Quest for Camelot (1998) gave its heroine the name Kayley just as the sound was surging across American playgrounds.
