Karrigan is a modern American adaptation of the Irish surname Ó Ciaragáin. It is derived from the Gaelic word 'ciar', meaning dark or black, often used to describe hair or complexion. While it shares phonetic similarities with the name Kerrigan, it is frequently chosen for its rhythmic, three-syllable sound.
