During the execution of Catherine Howard and Lady Rochford, it is depicted in the series that Lady Rochford was executed first. However, historically, Catherine Howard was executed first, followed by Lady Rochford.
It is considered apocryphal that Catherine Howard said on the way to her death "I die a Queen, but would rather die the wife of Culpepper." No eyewitness accounts of her execution support those words. Most accounts say she gave a typical statement.
Along with Lady Rochford, Culpepper, and Dereham, many of Catherine Howard's relatives were also arrested, tried, and sentenced to life imprisonment for concealing treason. The exceptions to this were the Earl of Surrey and his father, Catherine's uncle, the Duke of Norfolk who retreated to his home when the investigation began and wrote a letter distancing himself from the scandal and blaming his niece and stepmother.
Anne Seymour never had a child named Thomas.
Catherine Howard asks a man who comes in with food what is going on. The man Sir Edward Baynton was her brother in law. He was married to her elder half sister Isabel Leigh.
