[name_m]Keane[/name_m] reads pretty masculine to me personally, mostly because of the strong surname/Irish surname feel and the similarity to names like [name_m]Kane[/name_m], [name_m]Cian[/name_m], [name_m]Keenan[/name_m], [name_m]Dean[/name_m], etc. I wouldn’t be shocked to meet a girl named [name_m]Keane[/name_m], but my instinct would definitely be boy first.
It feels modern, cool, understated, slightly artsy/indie to me. I picture someone creative and calm rather than super sporty or hyper masculine. [name_m]The[/name_m] vibe I get is kind of sleek and minimalist - like [name_m]Rowan[/name_m], [name_m]Hollis[/name_m], [name_f]Arden[/name_f] or [name_m]Ellis[/name_m]. I think it works best if you like names that feel quietly stylish and uncommon without sounding invented.
