About Eliza de Feuillide

Eliza Capot, Comtesse de Feuillide was the cousin, and later sister-in-law, of novelist Jane Austen. She is believed to have been the inspiration for a number of Austen's works, such as Love and Freindship, Henry and Eliza, and Lady Susan. She may have also been the model from whom the character of Mary Crawford from the novel Mansfield Park is derived.
