In the Mistmantle Chronicles by M. I. McAllister (I think that's the correct spelling of her name), one of the characters, a squirrel, is named Crispin. He starts out as a captain, but he's banished because he's falsely accused for the prince's death. He returns to Mistmantle Island after Urchin (the main character) rescues him. When the king dies, it is his duty to become the next king, which he does. He's a very noble character with a very noble name, in my opinion.
