* "The Rose of Castile" by William H. G. Kingston (1860): This is a historical novel for young readers, and is the most likely candidate if you're remembering a story about Castille.
* "The Rose of Castile" by Joseph Sheridan Le Fanu (1862): This is a short story, not as widely known as Kingston's work.
* "The Rose of Castile" by Charles Lever (1863): This is another novel, and possibly the least known of the three.
Please provide more context or details if you can remember them. For example:
* What is the story about? (e.g. a queen, a princess, a love story, a historical event)
* Who are the main characters?
* What are the main themes or events?
