I love Arianna - Pronounced "Ah-ree-ah-na"

Also,

Eva/Ava
Isabella
Georgia/Georgina
Amaya
Hannah
Victoria
Savannah

I also love names that carry from baby to child to adult...

Something "Cute and Sweet" when they're young like "Awww look at little baby _____ she's so adorable!"

But "Strong, Mature & Classy" when they're adults - A name you could take seriously on the door of an office one day!

Good Luck!
