Anne Boleyn

Anne Boleyn was the second wife of King Henry VIII of England and the mother of Queen Elizabeth I. She was executed on 19 May 1536, shortly after meeting the Sixth Doctor and Peri Brown. (BFA: Recorded Time)

As it was suggested that the Tenth Doctor married Queen Elizabeth, it is possible that Anne Boleyn later became his mother-in-law. (DW: The End of Time)
