This is my (male) cousin’s middle name and I really like it! It does read sort of classic [name_f]Irish[/name_f] boyish. I could see it on a girl but with more of a “boyish name on a girl” vibe like [name_m]Anderson[/name_m], [name_f]Monroe[/name_f], Chandler…
[name_m]The[/name_m] names you listed definitely vibe well with [name_m]Keane[/name_m] in my opinion. Especially [name_m]Grady[/name_m], [name_m]Lowen[/name_m], and [name_m]Hayes[/name_m]. And, if you’re not bothered by the androgyny/femininity of [name_f]Shea[/name_f] or [name_f]Marlow[/name_f] then [name_m]Keane[/name_m] definitley would work.
