It’s a charming and unexpected set and I think it works - though if you want it to be really cohesive, I will say [name_f]Juniper[/name_f] feels a bit out of place - a modern choice, compared to the classic or vintage vibe of the others.
Thoughts / suggestions around individual combos:
[name_m]Gilbert[/name_m] [name_m]Arthur[/name_m] ‘Gil’ - this feels clunky cute, with a literary vibe about it too. [name_m]Gil[/name_m] is fun
[name_f]Beatrice[/name_f] [name_f]Louise[/name_f] - regal, strong and elegant. I don’t think ‘Bea’ stands out, though I would intuitively say it as ‘Bee’, so I would read it as one syllable anyway? Still, I don’t think it’s a big deal that the nickname was a different length.
Alternative middles:
[name_f]Beatrice[/name_f] [name_f]Phoebe[/name_f], [name_f]Beatrice[/name_f] [name_f]Pearl[/name_f], [name_f]Beatrice[/name_f] [name_f]Clara[/name_f], [name_f]Beatrice[/name_f] [name_f]Emilia[/name_f], [name_f]Beatrice[/name_f] [name_f]Matilda[/name_f], [name_f]Beatrice[/name_f] [name_f]Leona[/name_f], [name_f]Beatrice[/name_f] [name_f]Opal[/name_f], [name_f]Beatrice[/name_f] [name_f]Eleanor[/name_f] (nn Belle?), [name_f]Beatrice[/name_f] [name_f]Ivy[/name_f]
[name_f]Juniper[/name_f] [name_f]Maude[/name_f] - love zippy [name_f]Juniper[/name_f] and more grounded nn [name_f]June[/name_f]. [name_f]Juniper[/name_f] [name_f]Maude[/name_f] has balance and the nickname does make it blend more easily/cohesively into the set
Alternative middles:
[name_f]Juniper[/name_f] [name_f]Claire[/name_f], [name_f]Juniper[/name_f] [name_f]Sophie[/name_f], [name_f]Juniper[/name_f] [name_f]Charlotte[/name_f], [name_f]Juniper[/name_f] [name_f]Edith[/name_f], [name_f]Juniper[/name_f] [name_f]Ellen[/name_f], [name_f]Juniper[/name_f] [name_f]Daphne[/name_f], [name_f]Juniper[/name_f] [name_f]Sylvie[/name_f], [name_f]Juniper[/name_f] [name_f]Dorothy[/name_f]
[name_m]William[/name_m] [name_m]Clyde[/name_m] - a solid, strong classic - though it doesn’t quite have the flair of the other names - not a huge deal if you love it though. I would also hesitate about ‘Gil’ and ‘Will’ rhyming in the same set too.
