I’ve loved the name Willow since I was a child but unfortunately it really doesn’t work with our surname…very similar letters and sounds.
Looking for alternatives with a similar feel, I love whimsical, nature names 
EDIT: Bonus if it goes with our son’s name Caspar
[name_f]Daisy[/name_f]
[name_f]Clementine[/name_f]
Besides the similar-sounding [name_f]Willa[/name_f] (my DD’s name), here are some soft, breezy and enchanting nature names:
[name_f]Meadow[/name_f]
[name_u]Winter[/name_u]
[name_f]Wisteria[/name_f]
[name_f]Searose[/name_f]
[name_u]Solstice[/name_u]

[name_u]Florence[/name_u]
[name_f]Isabella[/name_f]
[name_u]Ivy[/name_u]

[name_f]Lily[/name_f]
[name_f]Maple[/name_f]
[name_f]Mirabelle[/name_f]
[name_f]Olivia[/name_f]
[name_f]Pearl[/name_f]
[name_u]Pepper[/name_u]
[name_u]Rose[/name_u]
[name_u]Sage[/name_u]
Wow what a beautiful collection, I’m feeling inspired!
[name_f]My[/name_f] favourite is [name_f]Primrose[/name_f] with nn [name_f]Posy[/name_f], absolutely love that. If I was feeling brave, [name_f]Meadow[/name_f] really appeals but I dont think DH would go for it!
I’ve always loved [name_f]Daisy[/name_f] too, always come back to [name_f]Daisy[/name_f] 
[name_u]Esme[/name_u] would be beautiful with [name_m]Caspar[/name_m]!
Some other whimsical ideas…
[name_f]Zara[/name_f]
[name_u]Prairie[/name_u]
[name_u]Lark[/name_u]
[name_f]Dahlia[/name_f]
[name_f]Blossom[/name_f]
[name_f]Seraphina[/name_f]
[name_f]Lumi[/name_f]
[name_f]Magnolia[/name_f]
[name_f]Astrid[/name_f]
[name_f]Birdie[/name_f]
[name_f]Poppy[/name_f]
[name_f]Sunday[/name_f]
[name_f]Eira[/name_f]
[name_f]Primrose[/name_f]
[name_f]Calista[/name_f]
[name_u]Fable[/name_u]
[name_f]Aurora[/name_f]
I also thought of [name_f]Elowen[/name_f] and [name_u]Waverly[/name_u], although they might have the same problem as [name_u]Willow[/name_u] with your surname.
I may have gone too hard on nature names that are less established - maybe [name_u]Ivy[/name_u] or [name_f]Iris[/name_f], or other word names, [name_u]Harper[/name_u] or [name_u]Piper[/name_u] - more likely to get across line with DH. I hope you can push for the stunning [name_f]Primrose[/name_f] though, it’s one of my fave names! I’ve also just got back into [name_f]Pomeline[/name_f] (meaning apples/appley) which could have nn [name_f]Polly[/name_f].
It’s a beautiful selection, I just know DH too well 
I just ran [name_f]Primrose[/name_f] past him though and he loves it so thank you! [name_f]Pomeline[/name_f] is gorgeous
