What does the name Kelli mean?

Kelli is a spelling of Kelly, pronounced the same way, so it shares Kelly's meaning and origin.

Kelly is the anglicized form of the Irish surname Ó Ceallaigh, 'descendant of Ceallach'. The personal name Ceallach is of uncertain meaning; it is often connected with ceall 'church' or with a word meaning 'bright-headed' or 'strife', and none is proved. Kelly is one of the most common surnames in Ireland. It was first used as a boys' first name in the US, then became mainly a girls' name from the mid-20th century; actress Grace Kelly helped.
