Dowager Duchess of Wigan

The Dowager Duchess of Wigan is the grandmother of Robert Beaumaris and the matriarch of a large family. She is the terror of four sons, three surviving daughters, numerous grandchildren, and many other dependents, but she is fondest of her late daughter Lady Mary, who she called Maria, and Maria's son Robert. Shortly before the events of Arabella, though, she told Robert not to visit her until he mended his ways.

She lives with her unmarried daughter Lady Caroline Caldicot in Wimbledon.
