This list is absolutely stunning! I love the idea of using [name_f]Florence[/name_f] on a boy, so unexpected and cool (especially with the nickname Rory). Some pairing ideas…
[name_f]Cosima[/name_f] & [name_m]Isidore[/name_m] (Cosy & Issy)
[name_f]Beatrice[/name_f] & [name_m]Lucien[/name_m] (Bea & Lucy)
[name_m]Bellamy[/name_m] & [name_f]Florence[/name_f] (Bella & Rory)
[name_f]Cosme[/name_f] & [name_m]Ira[/name_m]
[name_f]Vivien[/name_f] & [name_m]Casper[/name_m] (Viv & Cas)
[name_m]Enea[/name_m] & [name_f]Ariel[/name_f]
[name_m]Valentine[/name_m] & [name_f]Melrose[/name_f] (I wouldn’t worry about the VD initials, esp if they’re spaced out with a middle name)
[name_m]Leone[/name_m] & [name_m]Cecil[/name_m]
[name_f]Frances[/name_f] & [name_m]Clarence[/name_m] (Francie & Clary)
