They definitely sound like they belong together. There’s a lovely balance of softness and strength across all four names. I also love that the first names share a nice rhythm. [name_m]Cosmo[/name_m], [name_m]Samson[/name_m], and [name_f]Polly[/name_f] each have two syllables, while [name_f]Maeve[/name_f] has one, giving the set a natural flow without feeling too matchy.
[name_f][/name_f][name_m]Cosmo[/name_m] does feel a little more playful and adventurous compared to the more grounded feel of [name_m]Samson[/name_m] and [name_f]Maeve[/name_f], but not in a way that feels jarring, in fact, it adds a lively, interesting touch to the group and keeps the set feeling vibrant and dynamic.
[name_f][/name_f]I also really like the middle name choices. [name_m]Jay[/name_m] and [name_m]Crain[/name_m] give the boys a subtle bird theme, which is a lovely, meaningful connection, while the girls’ middle names match stylistically and add a beautiful, classic touch. Altogether, the names feel cohesive, distinctive, and rich with personal meaning.
