Amelia, just don't like that meeeeeel sound in the middle. I know it's very popular though so nobody else minds I think. I think of it as being a variation of Emily, and on that line of thinking I prefer Emily, or if you want to be different, Romilly, or Camellia. (like the flower)
Alice, very sweet but still strong, very classic. A really good name choice, but although I really like it, I'd use it in the middle. Just seems more like a middle name to me!
Anna. I really like this, it's very simple but not weak. It's not going to date like Ella or Emma will. Even though I really like Anna, I think some people might think it's not quite enough of a name... Maybe?
Annabel is a bit stronger imo. Can still be Anna if you choose, but Annabel Alice flows really well. I like Anna, I just feel I want to accessorise it!!
Dooes the name have to begin with A? I like Juliet Alice and it popped in to my head, or Juliet Amelia (I can take it in the middle).
