What does Kane mean?
The 'battle/warrior' sense comes from the Irish Ó Catháin, from 'cath' (battle). Flagged: Kane has several unrelated origins - Hawaiian 'man' (and a deity), a weakly attested Welsh 'beautiful', and Japanese readings - so only the Irish line carries the warrior meaning.
What does Quinn mean?
Quinn comes from the Irish surname Ó Cuinn, “descendant of Conn,” with Conn carrying the sense of “chief” or “wisdom.”
