Kaileigh is a unique, four-syllable feminine given name of Scottish origin. It is derived from the Scottish surname 'Cailleach', which translates to 'hag' or 'old woman'. This unusual etymology is believed to refer to the Cailleach Bheur, a figure in Scottish folklore often depicted as an old woman who symbolizes winter and stormy weather. The name Kaileigh has gained popularity in recent years, particularly in English-speaking countries like England and Australia. It is often misspelled or mistaken for similar names such as Kayleigh or Kaleigh.
"Kaileigh's popularity as a name peaked around the late 1990s to early 2000s with over 100 births per year from 2000 to 2004, but has since declined significantly, dropping below 50 births annually after 2016."
