Fiorella
Not only are individual flower names more popular (and exotic) than ever, but so too are the more generic names like Florence and Flora. While brother name Fiorello became known via long-term New York Mayor LaGuardia, the lovely Fiorella has never crossed cultures. She could join Arabella as a post-Isabella ella choice.
And speaking of Isabella, Fiorella is the first of the three middle names of Isabella Rossellini.
