I really like [name_m]Remy[/name_m] or [name_f]Remi[/name_f] for a girl, it’s got a stylish flair to it and feels fresh and cheerful. It would suit a lot of personalities eg I can imagine a tomboy [name_m]Remy[/name_m] or a girly girl [name_m]Remy[/name_m] easily.
[name_f][/name_f]I enjoy the idea of [name_f]Polly[/name_f] and [name_m]Remy[/name_m] as sisters, [name_f]Polly[/name_f] is more vintagey and obviously a girl name whereas [name_m]Remy[/name_m] is a bit more ambiguous and modern, but together they have a fresh bounciness I really like.
[name_f][/name_f][name_m]Solomon[/name_m], though, I’m less sure of [name_f][/name_f]- it’s grander and more old fashioned [name_f][/name_f]- I love it as a name but not sure it works stylistically with the others. Also, [name_f]Polly[/name_f] and [name_m]Solomon[/name_m] together? [name_f][/name_f]- you may end up with [name_f]Polly[/name_f] and [name_m]Solly[/name_m]!
[name_f][/name_f]From your lists, I’d pair [name_m]Solomon[/name_m] with [name_f]Eloise[/name_f] or [name_f]Florence[/name_f], whereas I’d pair [name_f]Polly[/name_f] with [name_m]Hugh[/name_m], and Remy/Remi with [name_m]Finnick[/name_m], [name_m]Elias[/name_m], or [name_m]Sullivan[/name_m].
