Name for a character?

As I mentioned before, I'm writing a historically-inspired, 18th-century story, sort of like Sleeping Beauty but not exactly; and I need a first name for the heroine.   Right now she's Briar-Rose; but that's terribly cliche, "Briar" doesn't sound so good by itself, and I'd rather not use a name from Sleeping Beauty, particularly since I've already (coincidentally and unintentionally) used another one from that story.  Ideas would be greatly appreciated!  :) 

I'd like a name that has a good nickname, or it could just be a short name.  Something that's a bit unusual, not too popular, and is easy to say.  She's a quiet character, a bit like Fanny Price from Mansfield Park, so it would be good if the name reflected that.
