The History of the Fairchild Family by Mary Martha Sherwood was a series of bestselling children's books in nineteenth-century Britain. The three volumes, published in 1818, 1842 and 1847, detail the lives of the Fairchild children. Part I, which was in print for over a century, focuses on Emily, Lucy and Henry's realization of their "human depravity" (original sin) and their consequent need for redemption; Parts II and III emphasize more worldly lessons such as etiquette and virtuous consumerism.
