I find the opposite - well, I like a lot of boys’ names but find it much easier to find and collate girls’!
Looking through the girl section of the forum to see what other names people are discussing/ considering should help you see new names and build up a list. That’s what I would do, and you could even start with one you’ve listed, on the general Nameberry search (ie look it up through the search function), then scroll to the linked similar names at the bottom and go on a little adventure with that, see how far you go and what you pick up on the way.
Not sure if you’re expecting or just wanting to build your list, but looking at what you’ve started with you’ve got a mix of frontier classics and more contemporary word-names, with a sort of epic/ancient world feel.
You could work in on making the ones you’ve shortlisted into first and second pairs or possibly the trendier names into nicknames for the classic ones. But either way, maybe building up two lists, one classic and one more hip & “out there”. Then see which list is easier to add to. Books and movies are other good sources of names (and, I don’t follow these, as here is enough for me but there are YouTube and Instagram accounts focused on names).
Here are some names you might like:
Florence
Penelope
Anastasia
Olympia
Valentina
Evangeline
Josephine
Victoria
Athena
Xanthe
Valerie
Leonor(e)
Lydia
Helena
Persephone
Guinevere
Cressida
Ophelia
Theodora
Or more contemporary (sounding, I mean):
Hollis
Journey
Indigo
Blair
Romy
Cleo
Blue
Aspen
Sunday
Riviera
Auden
Soleil
Zélie
Holiday
Finally, you don’t need a massive list to name a child, I’d go for a list of 10-20 you really love, after subbing in and out/ refining, and whittle down from there.
