There are countless fascinating and unbelievable stories in the Royal Family's history.
Whether it is a boy breaking into Buckingham Palace to steal Queen Victoria's underwear, an heir to the throne being accused of being Jack the Ripper or suggestions that an antlered ghost called 'Herne the Hunter' can be spotted in Windsor Great Park when a King or Queen is close to death.
