What a lovely list
Overall I get a stylish-but-approachable vibe, feminine but not too frilly or fussy, and they’re all names that would suit both a little girl and an adult.
[name_m]Not[/name_m] sure where you’re based but [name_f]Amelia[/name_f], [name_f]Florence[/name_f], [name_f]Poppy[/name_f], [name_f]Phoebe[/name_f], [name_f]Sienna[/name_f], [name_f]Grace[/name_f], [name_f]Margot[/name_f], [name_f]Penelope[/name_f] are all at the top end of the [name_f]England[/name_f] and [name_m]Wales[/name_m] chart so they feel familiar, but warm and friendly, to me. [name_f]Phoebe[/name_f] and [name_f]Margot[/name_f] are particularly charming imho and I like them as sisters. I know a mischievous little [name_f]Florence[/name_f] and love the nickname possibilities - [name_f]Florrie[/name_f], [name_f]Flora[/name_f], [name_f]Flossie[/name_f], [name_f]Floss[/name_f], [name_m]Wren[/name_m]! I find [name_f]Amelia[/name_f] bit overused (but can’t deny it’s pretty). If you’re not in the UK, I’d say you have very [name_f]British[/name_f] taste!
My favourites otherwise are [name_f]Daphne[/name_f] (adore her, but can’t get my husband on board!!), [name_f]Serena[/name_f], [name_f]Tallulah[/name_f], [name_f]Celine[/name_f], [name_f]Eloise[/name_f], and [name_f]Sadie[/name_f] - love [name_f]Sadie[/name_f], so cheerful and a little bit retro.
My least favourites are probably [name_f]Lila[/name_f] and [name_f]Elle[/name_f], they seem a bit nonspecific compared to the other options.
I also notice you’ve got top Bridgerton faves [name_f]Daphne[/name_f], [name_f]Penelope[/name_f], and [name_f]Eloise[/name_f], which might be best avoided in the same sibset unless you are a mega fan!
[name_f]Hope[/name_f] that helps
