Kelly (given name)

Kelly is a unisex given name derived from an Anglicized version of the Irish masculine name Ceallach or a transferred use of the Irish surname O'Ceallaigh. O'Ceallaigh, which means "descendant of Ceallach", was Anglicized as Kelly or O'Kelly; the meaning of the personal name Ceallach is uncertain. It could mean "bright-headed," or "strife" or "monastery church" in Irish. As a name of Irish origin, the Kelly surname is partially an anglicised version of older Irish names, especially Ó Ceallaigh, though the name Kelly is also present to a lesser extent in other Celtic cultures. Kelly is historically a male-only name, but has been used as a female given name since the 1960s, though with a significant minority usage as a masculine name, especially within Celtic families.
