Keyllie is English in Origin.

Keyllie is a modern, inventive spelling that blends the sounds and traditions of Kelly, Keeley, and Kaylee. As such, it draws on Irish roots: Kelly comes from the surname Ó Ceallaigh (“descendant of Ceallach”), whose meaning is debated - often interpreted as “war/strife” or “bright-headed” - while Keeley/Keeley traces to Ó Caolaidhe, from caol “slender.” Through Kaylee, it also connects to the American practice of combining Kay (a short form of Katherine, “pure”) with Lee (“meadow/clearing”). The result is a contemporary name with layered, sometimes overlapping meanings rather than a single fixed sense.

Usage of Keyllie is recent and rare, emerging alongside the late-20th-century rise of -ee/-ie ending names in the US and elsewhere. Closest variants and cognates include Keylie, Keylee, Kaylee, Kailey, Kayleigh, Keely/Keeley, Kelly/Kellie. Typically feminine today, it sits near Kelly’s unisex history. Nicknames: Key, Kiki, Ellie, Lili.
