History & Origin
Kayley has a double pedigree. As an Irish surname, Kealy or Keeley descends from Ó Caollaidhe, rooted in caol, 'slender'; as a modern given name, it usually represents a blend of Kay — itself short for Katherine — with the popular -ley ending, part of the same family as Hayley and Bailey. Some parents also connect it to the Irish céilí, the festive social dance.
The Kaylee sound exploded in late twentieth-century America in a dizzying array of spellings — Kaylee, Kayleigh, Kaylie, Kailey, Kayley — 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.
