From the Irish surname Ó Cathasaigh, whose byname 'cathasach' derives from 'cath' (battle) and is usually glossed 'vigilant, watchful' (in war); a secondary reading is 'noisy'.
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.
Casey is more popular than Kane today: about 1,072 US babies were given the name Casey in 2025, compared with 695 named Kane.
