Anne de Bourgh is a character in Pride and Prejudice. She is the only child and heir of the late Sir Lewis de Bourgh and the Lady Catherine. The current Earl Fitzwilliam is her maternal uncle, and his three sons, including Colonel Fitzwilliam, are a few of her cousins. Lady Anne Darcy is her maternal aunt, and thus she is also a close relation of the Darcy siblings, Fitzwilliam and Georgiana. Her relations on her father's side are unknown, but she is the heir to Rosings Park because there was no entail. Her date of birth is unknown, but since she was born around the same time as Mr. Darcy, they are about the same age. She resides at Rosings Park in Kent with her mother.
