Anne Mortimer (December 27, 1390 - September, 1411) was the daughter of Roger Mortimer, 4th Earl of March (1373-1398), and a great-great-granddaughter of King Edward III of England. It was through her that the House of York claimed the throne of England; however, little is known of her life.
Anne was descended from King Edward through one of his older sons, Lionel of Antwerp, which gave her a claim on the throne after the death of her father and siblings. In about 1406, she married Richard, Earl of Cambridge, who was also descended from Edward III through a younger son. They had two children, Isabella and Richard, Duke of York, who later laid claim on the throne, beginning the Wars of the Roses. It is believed that Anne died giving birth to him.
