Maybe this is just me but I’m liking the four syllable names cadence-wise? I like previous suggestions of [name_f]Amaryllis[/name_f] and [name_f]Magnolia[/name_f].
(Quick question: does nature inspired mean it can have a nature meaning or that it should literally be a nature word?)
[name_u]Quinn[/name_u] [name_f]Serafina[/name_f] or [name_u]Quinn[/name_u] [name_f]Seraphina[/name_f] (fire)
[name_u]Quinn[/name_u] [name_f]Cordelia[/name_f] (sea) (too matchy with the first sounds? Up to you)
[name_u]Quinn[/name_u] [name_f]Iolanthe[/name_f] (violet flower) (I’ve seen this pronounced both yo-lan-thee and eye-oh-lan-thee but I’d favor the second pronunciation here personally)
My favorite of these would be [name_u]Quinn[/name_u] [name_f]Serafina[/name_f]/[name_f]Seraphina[/name_f]. Good luck!
My first thought was [name_u]Quinn[/name_u] [name_f]Willow[/name_f]. Assuming you haven’t used it already, I quite like [name_f]Willow[/name_f] with [name_u]Quinn[/name_u]. A few other ideas:
[name_u]Quinn[/name_u] [name_u]Ainsley[/name_u]
[name_u]Quinn[/name_u] [name_f]Violet[/name_f]
[name_u]Quinn[/name_u] Larkspur
[name_u]Quinn[/name_u] Estellle
[name_u]Quinn[/name_u] [name_f]Heather[/name_f]
[name_u]Quinn[/name_u] [name_f]Aurora[/name_f]
[name_m]Just[/name_m] loosely based on is acceptable. We have Alder and [name_m]George[/name_m] as the other two kid’s middle names. [name_m]George[/name_m] being a name that barely makes it nature wise.
