William Brereton, English courtier (born 1487)

William Brereton, c. 1487/1490 – 17 May 1536, was a member of a prominent Cheshire family who served as a courtier to Henry VIII. In May 1536, Brereton was accused of committing adultery with Anne Boleyn, the king's second wife, and executed for treason along with her brother George Boleyn, Henry Norris, Francis Weston and a musician, Mark Smeaton. Most historians are now of the opinion that Anne Boleyn, Brereton and their co-accused were innocent.
