Thanks for all the responses so far! There are so many I haven’t thought of before, and plenty that I already do love – you guys have nailed my style, I think.
@Greyblue
I have never really considered [name_f]Tilda[/name_f] before, but I actually think it’s quite cute!
I do like [name_f]Matilda[/name_f], too, as @TDFM suggested. 
@jonquils
[name_m]How[/name_m] charming is [name_f]Mirabelle[/name_f]! Loving the nn options ‘[name_f]Miri[/name_f]’ and ‘[name_f]Belle[/name_f]’, too.
@SparkleNinja18
I do love [name_f]Sophie[/name_f]!! She’s so sweet. [name_f]Sophia[/name_f] is also lovely, and the [name_f]Rose[/name_f] names, too (though I think I still prefer simple, classic [name_f]Rose[/name_f]).
@juliem1912
YES. I adore [name_f]Eleanor[/name_f]!
@katinka
Ooh, I quite like [name_f]Sabine[/name_f]! Certainly not one I’ve ever considered before, but it is so elegant. Definitely adding to my long list. (Might be a new crush!)
@AdroitArtemis
[name_f]Eloise[/name_f] is so sweet! Definitely a classic I often overlook.
@Estrela
[name_f]Dahlia[/name_f] is gorgeous!
@hyacinthbucket
I think [name_f]Cynthia[/name_f] is quite pretty and often underrated. However, it’s my aunt’s name, so it’s not really an option for me. But it does remind me of [name_u]Hyacinth[/name_u], as the two names were a mother-daughter pair in a favorite book of mine (Wives & Daughters). And I definitely love your description of the name – 100% agree! 
@GoogleChrome
[name_u]Love[/name_u] [name_f]Hannah[/name_f] & [name_u]Marie[/name_u] both – especially [name_u]Marie[/name_u] as it’s so unexpected as a fn these days!
