Age
Lady Anne is likely of an age with Lady Catherine. We know that she’s deceased by the beginning of the novel. We never receive details on the specifics of her death, but we know it couldn’t have been more than 16 years ago, evidenced by Georgiana’s presence.
Family and Situation
Lady Anne was the daughter of The Late Earl of -----, making her the sister of Lady Catherine de Bourgh and the current Earl of -----. She married Mr. Darcy of Pemberley and was mother of Fitzwilliam Darcy (to whom she leant her maiden name) and Georgiana Darcy. As she married a wealthy commoner, it is possible that Lady Anne either had a name but an insignificant dowry or married for romantic notions of love. Given Darcy’s resistance to imprudent matches, it’s likely that it was the former.
Character
Lady Anne is rarely mentioned by any of the characters in the novel. Lady Catherine asserts that they planned for the eventual union of Fitzwilliam Darcy and Anne de Bourgh, but this information is never confirmed from a second source.
