Anne Spencer, Countess of Sunderland (d. 1715)

Anne Spencer, Countess of Sunderland, originally Anne Digby (c. 1646–April 26, 1715) was the wife of Robert Spencer, 2nd Earl of Sunderland and the daughter of George Digby, 2nd Earl of Bristol. Her mother was the former Lady Anne Russell.

Anne married Spencer on June 10, 1665. She was a lady-in-waiting for Mary of Modena during the reign of James II, and she was present at the birth of the Prince of Wales, signalling to the king that his new child was a boy.

She became a close friend of Sarah Churchill, later Duchess of Marlborough, and was not liked by Queen Anne, who was jealous of their friendship. She is alleged to have had an affair with Henry Sidney, Earl of Romney, her husband's uncle. However, John Evelyn spoke well of her.

She had at least five children by Sunderland, only one of whom outlived her:

*Lord Robert Spencer (1666–1688)
*Lady Anne Spencer (1667–1690), married James Hamilton, 4th Duke of Hamilton in 1687
*Lady Isabella (1668–1684)
*Lady Elizabeth Spencer (1671–1704), married Donough MacCarty, 4th Earl of Clancarty in 1684
*Charles Spencer, 3rd Earl of Sunderland (1674–1722), who married Arabella, daughter of Henry Cavendish, 2nd Duke of Newcastle in 1695, then Anne Churchill, second daughter of John Churchill, 1st Duke of Marlborough and Sarah Churchill in 1700.
