Every family has its secrets, and in the case of the British royal family, this is especially true. A season four episode of The Crown, entitled “The Heredity Principle” delved into one particular shocking family secret. The story which follows is a sad one, and perhaps more of an indictment of the times in which it took place, rather than the people who played a role in it coming about.

Born in 1919 and 1926 respectively, Nerissa and Katherine Bowes-Lyon were two of the daughters of John Herbert Bowes-Lyon and his wife Fenella. John was the brother of the queen mother, and so Nerissa and Katherine were first cousins of Queen Elizabeth. Sadly, though, they were never able to be a part of the royal family.
