A sketch of Jane Parker, Lady Rochford, by Hans Holbein. Jane Parker was the vindictive wife of George Boleyn, Lord Rochford. George was Anne's brother, and Jane gave testimony against the siblings, alleging sexual misconduct. Jane Parker would later act as the bawd for Henry VIII's fifth wife (and Anne's cousin) Katherine Howard. Fittingly, Jane Parker would be beheaded for her role in arranging trysts for her mistress.
Catherine Howard (1523-1542) was Queen of England & the 5th wife of King Henry VIII. They married in 1540 almost immediately after the annulment of his marriage to Anne of Cleves. However Catherine Howard was beheaded after less than two years of marriage to Henry on the grounds of treason for committing adultery while married to the King.
