Girl names that go with Belle

Brianne
My husband and I are ttc, but we're always on the lookout for name ideas. 
We have already decided that if we were to have a girl, we want to use the middle name Belle (it's my great grandmother's middle name), but we can't think of any good first names to go with it. 
Suggestions?
Edit: Forgot to add that our last name is Nelson, so it needs to go with that 😊
