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 4 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)
