Mary, Princess of England, consort of Frederick, Duke of Gloucester (1776 -1857)
Princess Mary was the eleventh child and fourth daughter of George III and Queen Charlotte. Mary had a sheltered upbringing and spent most of her time with her parents and sisters. She was married on 22 July 1816, to her first cousin, Prince Frederick, Duke of Gloucester and Edinburgh, the son of George III's brother, Prince William Henry, Duke of Gloucester and Edinburgh, at the Chapel Royal in St James's Palace. The couple lived at Bagshot Park, but after William's death in 1834 she moved to White Lodge in Richmond Park. They had no children. Princess Mary was the longest-lived (at 81 years) and last survivor of George III's fifteen children.
