I'd like to dispute the definition of
Kayleigh as being a common anglicization of ceilidh. I cannot find any instance where kayleigh is used as a anglicized spelling for ceilidh, the Scottish dance or social gathering, either before or after 1985. Where a phonetic pronunciation of ceilidh is provided, I've seen kaylee, kailey, cayley, and kay-lee, but usually ceilidh was used when referring to the gathering in English. Using thr name
Kayleigh as an example pronunciation appears later in the 2000s. There was no common anglicization.
Both
Kayleigh and Ceilidh appear for the first time in Scottish name statistics (back to 1974) at the same time, 1985. That's the same year Marillion released their song "
Kayleigh". There are examples of both
Kayleigh and Ceilidh being recorded used as names before 1985, but they number in the 10s across the available information for 3 countries (US, UK, Australia) and none in Scotland. In the Scottish stats pre-1985 there are two Caley, 1 Cailey, 1
Caleigh, 1
Kayley and 1 Kailie. Most instances of Ceilidhs born before 1985 were likely named one of the other spellings and then changed to the perceived correct spelling. There are two Ceilidh that were named in 1985 so from the beginning of the
Kayleigh trend people were connecting the name to the word spelling. Although the writer of the song
Kayleigh,
Derek Dick aka Fish, is Scottish, he has said the name is a combination of
Kay and
Leigh, inspired by a woman whose first two names were
Kay Lee.
I have only found one published name dictionary that defines
Kayleigh as an anglicization of ceilidh and that's the
Collins Dictionary of Scottish Names published in 2009. (But I see the entry is from 2007). Most others give it as a variant spelling of
Kaylee (which showed up in name books just a couple years before
Kayleigh) or as a combination of
Kay and Leigh/Lee. The first time I found it connected to ceilidh was in a 1988 American romance novel My Wicked Enchantress, where the main character
Kayleigh explains she was named after the Scottish social gathering ceilidh. Author
Julia Cresswell seems to address that in The Tuttle Dictionary of First Names in 1992: "This girl’s name, which is currently enjoying enormous popularity, is probably best analysed as a blend of
Kay and
Leigh rather than a phonetic rendering of the Gaelic ceilidh (‘party’). As with so many recently fashionable names, the sound is probably more important than the sense, for the name completes a set with other recently fashionable names, KELLY and KYLIE."
May I suggest the entry for
Kayleigh be updated to be a combination of
Kay and
Leigh, and use the song as the origin for the popularity of the name? This is the more widely supported origin.
