I know a couple who are Amelias. I don't like Amelia, personally, no offense, but it is definitely the very popular option, at least out here. (Australia.)
Dark horse options only I like: Romilda, Camellia. Camille would make more sense than Camellia, admittedly, but Camellia makes as much sense as Amelia, and I like the flowers.
I know a little girl who is 2 and named Milliana. The nn Millie would come easily with this name!
