Catherine Brydges, c.1524-April 1566, was the daughter of John Brydges, 1st baron Chandos (March 9, 1491/2-April 13, 1557) and Elizabeth Grey (d. December 29, 1559). She was a lady of the privy chamber to Queen Mary. In early 1556, she married Edward Sutton, baron Dudley (d. July 9, 1586) and soon after found herself being questioned about her brother-in-law, Sir Henry Dudley, the conspirator. Her husband was imprisoned for debt in 1559, by which time Catherine had given birth to a daughter, Anne (d.1584+).
