Thomas Seymour, 1st Baron Seymour of Sudeley, KG, PC (c. 1508 – 20 March 1549) was a brother of Jane Seymour, the third wife of King Henry VIII. With his brother, Edward Seymour, 1st Duke of Somerset and Lord Protector of England, he vied for control of their nephew, the young King Edward VI (r. 1547–1553). In 1547, Seymour married Catherine Parr, the widow of Henry VIII. During his marriage to Catherine, Seymour involved the future Queen Elizabeth I (then 14 years old), who resided in his household, in flirtatious and possibly sexual behaviour.
