Cheerful but laidback, surname-style Delaney is derived from the Old Irish name Dubhshláine and has become a familiar choice for girls in recent decades. Nevertheless, it has also been used for boys since the early 1900s and was equally - though rarely - given to both, right up until the 1990s. 
 
Since then, it has been given to around 15 boys each year, with notable bearers including musician Delaney Bramlett, actor Delaney Williams, and singer Delaney Davidson. With last names as first names on trend and <a href="the-softer-side-of-boys-names">soft names for boys</a> climbing the charts, Delaney could work well - and feel fresher - on a boy.

Derived from the Old Irish name Dubhshláine, Delaney can mean "dark challenger" or "dark river" depending on which translation is used. Alternatively, it could be an English surname, taken from the Old French de l'aunnaie", meaning "from the alder grove".

Only ever given to a handful of babies each year since the early 1900s, Delaney leapt up the charts in the 90s, It's rise in popularity could be attributed to its similarity in sound or style to the likes of Mackenzie, Destiny, Kimberly, or Kaylee, or it may be that parents liked it as a fresh twist on Elaine and a new way to the nickname Lainey. 
 Alternatively, pop cultural influences might have driven the name up the charts, with singer Delaney Bramlett releasing new music, actress Dana Delany starring in the successful TV drama, China Beach , and the Delaney family in The Baby Sitters Club book series.
