Last name for the name Scarlett?

My protagonist in one of my stories is supposed to be called Scarlett. However, I can't think of a suitable last name.

Short description about Scarlett:

Dark brown hair, green eyes, small, and slim. She's a dreamwalker, meaning she can see and influence other people's dreams. She's usually in a good mood and helpful, but also very suspicious.

It would be important to me that the name be a bit more unusual than, say, Clark, Baker, or Johnson. Oh, and please, nothing German.
