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 Murphy mean?
From the Irish surname Ó Murchadha, from 'muir' (sea) and 'cath' (battle), giving 'sea-warrior' or 'sea-battler'. One of the most common surnames in Ireland, now used as a given name.
