congratulations!!
your list is beautiful!!
[name_f]Alyssa[/name_f] - I’m not the biggest fan of [name_f]Alyssa[/name_f], I’m sorry. It was very popular when I was younger, so it does feel a bit overused and dated to me. I do, however, really like nn Lissy!!
[name_f]Aurora[/name_f] - I’m a bit biased on this one, it’s my niece’s name. I just think it’s so beautiful though. It’s sweet and magical, and both the borealis association & mythology association are wonderful. I also think its great that it suits all different types of people! I’ve seen other people say it isnt the easiest to pronounce, so that’s something to keep in mind, but my niece has never had any issues! If it helps, she also really likes her name. She’s gotten compliments on it her whole life!! (Also, not sure if you’re concerned about it being “too disney”, but she stopped getting princess comments a long time ago!)
[name_u]Brooke[/name_u] - I’ve always liked [name_u]Brooke[/name_u], it’s such a pretty name! I love the sound and the imagery it gives. While [name_f]Alyssa[/name_f] feels dated, I think [name_u]Brooke[/name_u] still feels fresh and current. It also fits in perfect with other currently popular nature names!
[name_f]Delilah[/name_f] - [name_f]Delilah[/name_f] is lovely. Very soft, sweet, and gentle. I do think it’s a bit popular though. I also want to mention that you/she will probably get a lot of “Hey There Delilah” comments! not a bad association, just a strong one. [name_m]Even[/name_m] the young Delilahs I know get these comments all the time!
[name_u]Dove[/name_u] - one of my absolute favorite names!! Its absolutely gorgeous. great imagery, so soft but with a hint of edge. [name_u]Dove[/name_u] [name_u]Cameron[/name_u] is a well known actress amongst the young ones too, so I think that makes the name feel familiar. Also fits in with other popular word/nature names!! I think this goes best with your surname, as well.
[name_u]Eden[/name_u] - [name_u]Eden[/name_u] is very sweet. I slightly prefer it on a boy myself. [name_f]Edie[/name_f] is so adorable though! I have seen other people think this name is heavily associated with religion though, just wanted to mention that just in case!
[name_f]Jasmine[/name_f] - [name_f]Jasmine[/name_f] is very pretty. a tiny bit dated, but not too much. I can absolutely imagine a little [name_f]Jasmine[/name_f]. It does make me think of the Disney princess, but I dont think that’s a bad association to have! They did come out with the new live action not too long ago, so that may be a pretty strong association at the moment though.
[name_u]Nova[/name_u] - love [name_u]Nova[/name_u] so much, for any gender! It’s cool and edgy, but still beautiful, sweet, and magical. I think [name_u]Nova[/name_u] fits all different types of personalities too. Personally, I’d love to be called [name_u]Nova[/name_u]! The space association is great too!
[name_u]River[/name_u] - [name_u]River[/name_u] is so sweet, another one I like on any gender. I love the nature association and the imagery this name has. I do think it’s becoming increasingly more popular though (amongst all genders), so that might be something to consider!
Roslind - this is pretty, but I do think it could cause some pronunciation/spelling issues for your little one. I think [name_f]Rosalind[/name_f] is more familiar which could cause some problems. It’s a lovely name though!
[name_u]Saylor[/name_u] - not the biggest fan of [name_u]Saylor[/name_u], sorry. It’s a sweet name, but it feels extremely trendy, especially compared to the rest of your list. However, it does feel more unisex (just like River), if that’s the vibe you’re going for! I do prefer the [name_u]Sailor[/name_u] spelling myself.
[name_f]Stella[/name_f] - a lovely classic!! its starry and magical, a beautiful name!
my overall favorites are [name_f]Aurora[/name_f], [name_u]Dove[/name_u], and Nova!! 
Good luck!!
[name_f]Aurora[/name_f] is pretty. It’s bold & feminine has awesome nature imagery. A tad popular if that worries you.
