Fanny Price is a young girl from a large and relatively poor family, who is taken from them at age 10 to be raised by her rich uncle and aunt, Sir Thomas, a baronet, and Lady Bertram, of Mansfield Park. She had previously lived with her own parents, Lieut. Price and his wife, Frances (Fanny), Lady Bertram's sister. She is the second child and eldest daughter, with seven siblings born after her. She has a firm attachment to her older brother, William, who at the age of 12 has followed his father into the navy. With so many mouths to feed on a limited income, Fanny's mother is grateful for the opportunity to send Fanny away to live with her fine relatives.

The story follows the main character Elizabeth Bennet as she deals with issues of manners, upbringing, morality, education, and marriage in the society of the landed gentry of early 19th-century England. Elizabeth is the second of five daughters of a country gentleman living near the fictional town of Meryton in Hertfordshire, near London.
