A new three-part series called The Queen’s Lost Family based on the archives of Princess Mary, Princess Royal and Countess of Harewood will air on Channel 4 from today.
The series will tell the story of the royal family from the 1920s to the under of the Second World War and draws from personal letters, diaries and photo albums held at Harewood House. It would be the first time that the Princess Mary Archive has been so comprehensively explored.
The archive is over 170 boxes but has never been fully catalogued. It was loaned to the Harewood House Trust in 2018, and this will enable cataloguing to take place over time.
