Princess Cordelia was presumably born into some kind of royal household hence the title of Princess, but her last name is not mentioned in any of the object descriptions, nor is there any mention of her parents or any siblings, however due to her retaining the title of Princess it is quite likely that she does have a living parent or grandparent with monarch status. She adored tea, and Princess would come from across the lands to have tea with her, but she much preferred the company of pirate captains, and she would end up dating a total of 3 pirate captains throughout her life.
