In the 18th and 19th centuries, to become Mistress of the House was the natural prospect of women born into Britain’s wealthy aristocratic families. An advantageous marriage would bring with it an important ancestral home—a visible expression of power, prestige, and good taste. Rosemary Baird introduces us to ten of these remarkable women, detailing their accomplishments in the creation and running of Britain’s great houses. We also learn about their education and training, the marriage market, and their obligations as leaders of fashion, interior design, and society. Based on diaries, letters, and family archives, Mistress of the House is a fascinating work of social history. Rosemary Baird was educated at Cambridge and Oxford; a former consultant at Sotheby’s, she is now Curator of the Goodwood Collection.
