Princess Charlotte of Wales was a fan of Jane Austen, and didn't even know it. When her uncle, the Duke Of York, lent her a copy of Sense and Sensibility, written by an anonymous lady, he believed, and so did Charlotte, that it was written by a certain Lady Anne Paget. Charlotte loved the book and related to its heroine Marianne:
"'Sence and Sencibility' I have just finished reading; it certainly is interesting, & you feel quite one of the company. I think Maryanne & and me are very like in disposition, that certainly I am not so good, the same imprudence, &c, however remain very like."
