I think Leilani is very sweet, I like it very much. As for the rest of your list, they’re all nice but I think personally that Klailea is a bit mouthful though pretty
I also think Lilo is nice, but the connection to Lilo and Stich is maybe too strong? Naia is cute an means dolphin
Edit: Would also like to suggest Kailani, Malia, Alamea, Luana, Noelani
We have a news reporter locally that is [name_f]Noelani[/name_f]. When she’s out in the field live and talking to other reporters they call her [name_m]Noe[/name_m]. It’s adorable. It’s meaning is [name_f]Heavenly[/name_f] Mist.
I love Hawaiian names! My favorite is Auli’i, like the actress Auli’i Cravalho who plays [name_f]Moana[/name_f] (another great Hawaiian name!). It’s pronounced ow-[name_u]LEE[/name_u]-ee. I don’t have the guts to use it as a first name since I’m not the least bit Hawaiian but I’d use it as a middle in a heartbeat.
