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.
