Jane Boleyn was sister in law, and confidante, to one of England’s best known Queen Consorts - Anne Boleyn. She saw firsthand the rise and fall of the Boleyn family, and was later accused of participating in their downfall. However the claims that she accused her husband of incest with his sister are unproven, and there is little evidence that she had anything to do with their executions.
