Keylley is Irish in Origin.

Keylley is a modern English given name most plausibly a stylized respelling within the Kelly/Kayley family. As a Kelly/Kelley offshoot, it traces back to the Irish surname Ó Ceallaigh, from the personal name Ceallach; scholars differ on its sense, proposing “war/strife,” “bright-headed,” or a tie to ceall “church/monastery.” If read as a Kaylee‑type blend (Kay + Lee), additional etymologies include Katherine’s “pure” and Old English leah “clearing, meadow.”

Used primarily in the late 20th and early 21st centuries, Keylley reflects the broader trend for inventive spellings in Anglophone baby names and remains rare compared with core forms. Likely pronunciations are KEL-ee or KAY-lee. Close variants include Kelly, Kelley, Kelli, Kellie, Keyley, Keylee, Keely, Kaylee, Kayley, Kailey, and Keeley. The name functions unisex in the Kelly lineage but skews feminine when associated with the Kaylee spellings.
