I posted recently but I’m still unsure of which to go with. I hope you can help me decide!
Leona/Leonie
Marlowe
Solenne nn Soley
Just speaking for me, I absolutely love Marlowe. I think it’s the most versatile in that it feels distinctly feminine and suited to a little girl, but just as easily suits a more masculine person because of its closeness to Arlo and Milo.
Marlowe is my favorite–it feels bright, fresh, and full of energy! All of your choices are lovely, though. If Soley on its own were an option that would be a close contender for me with Marlowe.
My vote is for Leona! Its the perfect mix of trendy yet slightly traditional which is what I tend to go for!
Love Marlowe so much! Leona and Solene are lovely too 
I don’t love Leonie and Solenne isn’t my style. I really like Leona and Marlowe though! If I had to choose, I slightly prefer Leona (Luna is my favorite name, so I’m sure that’s why.) And Leona Marlowe would be a great combo!
Honestly though either Marlowe or Leona would be a wonderful choice. You could always wait til the baby is born and see which one suits her more. Best of luck deciding!
Marlowe gets my vote.
I lie Leona Marlowe.
I just love Leonie. It’s one of my personal favorites. 
The meaning “lioness” is just so unbelievably cute! 
[name_u]Marlowe[/name_u]
I love the flow and charm of [name_f]Leonie[/name_f]
leonie is my favourite!
[name_f]My[/name_f] vote is for [name_f]Leonie[/name_f] or Leona! It’s feminine and familiar, but uncommon enough that she won’t have a bunch of classmates with the same name.
I don’t like [name_f]Solenne[/name_f] as a first name, and [name_f]Soley[/name_f] makes me think of shoe soles or the word solely. I like Sunny, Lenne, or [name_f]Lena[/name_f] better as nicknames honestly. I think it would make a lovely middle name though! I think [name_f]Leonie[/name_f] Solenne, [name_f]Leona[/name_f] Solenne, and [name_u]Marlowe[/name_u] [name_f]Solenne[/name_f] all sound good.
[name_u]Marlowe[/name_u] is NMS at all, and I imagine it on a boy. Maybe Marley? It feels much more feminine to me and still has that surname vibe to it.
[name_u]Marlowe[/name_u] gets my vote! Good luck with everything
[name_f]Leonie[/name_f] is so cute and beautiful
lovely ! my favourite is marlowe. it’s rich and timeless, and I love the literary connection.
marlowe is lovely!
[name_u]Love[/name_u] these names! I slightly prefer Marlowe, with [name_f]Leonie[/name_f] a close second.
[name_f]My[/name_f] favourite is Marlowe!
I absolutely love [name_u]Marlowe[/name_u] she’s in my top 20 I have the combination [name_u]Marlowe[/name_u] [name_f]Eliza[/name_f] [name_u]Wren[/name_u] on my list and it’s a name that I love. [name_u]Marlowe[/name_u] is such a spunky vibrant name with a really pretty sound.
I love Leona! I think that is such a beautiful name. So elegant and beautiful. You have some cute nickname options as well.
