I love your boys’ names, [name_m]Owen[/name_m], [name_m]Bennett[/name_m], and [name_m]Samuel[/name_m] are such a strong, cohesive set: classic, familiar, but not overused. I’d definitely aim for something that sits in that same ‘timeless but warm’ space.
[name_f][/name_f]On [name_f]Eva[/name_f], I don’t think you’re overthinking it. Sometimes a name we’ve loved forever just doesn’t feel right anymore once we hear it in real life. [name_f]Eva[/name_f] is beautiful and classic, and works well with yours boys names, [name_f][/name_f] but if it’s lost that spark for you, I’d trust that instinct.
[name_f][/name_f]From your list, I think [name_f]Blair[/name_f], [name_f]Violet[/name_f], and [name_f]Nora[/name_f] fit your sibset especially well, they feel stylistically in line with your boys without being too matchy. [name_f]Colette[/name_f] and [name_f]Esme[/name_f] are lovely too, though they lean slightly more French/chic than your boys’ names (not a bad thing, just a slightly different vibe).
[name_f][/name_f]You’ve had so many great suggestions so far, so I’ll try not to repeat:
