Orabella makes me think of someone with a cockney accent saying "horrible". 'orrible! It sounds like the kind of name that belongs in the Addams family. Can't you just see an Aunt Orabella Addams? For that reason, I kinda like it. It's very storybook-y.
Hippolyta is another one I like for its ridiculousness. I love the sound of
Hippolyta. There's also the form Ippolita, which is fun.
