Keilly Origin and Meaning

The name Keilly is a boy's name.

Keilly is a masculine name that appears to be a modern variant spelling, possibly of Kelly or Keily. Originally an Irish surname derived from 'Ó Ceallaigh' meaning 'descendant of Ceallach' (which referred to 'bright-headed' or 'troublesome'), it transitioned to use as a given name. While Kelly became more commonly associated with girls in the latter 20th century, Keilly with this particular spelling retains usage as a masculine name in some communities. The distinctive 'ei' spelling gives it a unique visual quality while maintaining the familiar pronunciation. Keilly remains rare in mainstream usage, making it an uncommon choice that stands out while still having recognizable roots. Regional and cultural variations may affect how the name is perceived and pronounced.
