Kelly
Kelly is a gender-neutral name of Irish origin that easily makes a bright first impression. A modern Anglicized form of the Irish last name Ó Ceallaigh (or the given name Ceallach), Kelly comes packed with rich history and old Irish charm. While Kelly is most often translated as "bright-headed," its precise root is still up for debate for some etymologists. Other possible meanings include "war," "strife" and "frequenting churches"—bringing the heat, but also bringing the peace. No matter its meaning, Kelly is a classic choice with endless shine.
While historically used as a last name across the Emerald Isle, Kelly made a massive splash in the mid-to-late 20th century as a stand-alone given name. It soared into high popularity for both boys and girls in the US and quickly became a gender-neutral staple. Pop culture is full of famous namesakes to inspire your starlet, including iconic singer Kelly Clarkson, actress Kelly Ripa, TV personality Kelly Osbourne and former professional surfer Kelly Slater. Lightweight, friendly and oh-so bright, Kelly continues to be a timeless favorite for parents everywhere.
