What is a good name for a angel?

I always been so fickle on names for my characters, especially my protagonist that I seem to be self-absorbed with. The principle character of my children's novel (aimed for children between the ages of 9 to 12) is one little, over inquisitive angel. I thought, maybe she could remain unnamed and I can just call her "the angel" throughout the story. But it doesn't feel quite right to me, I think she deserves a name. Can you suggest some simple, short and tasteful names for her? Her hair looks as if wild flames were circling her head, her skin fair and clear where it isn't freckled, and has eyes like summer storms (an imagery for large and eyes), if that compels you get a visual of her.
