Dame Ann Parker Bowles (née de Trafford; 14 July 1918 – 22 January 1987)[2] was a British aristocrat and Girl Guides leader.
Ann de Trafford was born in 1918 at 29, Portland Place, London, the eldest daughter of millionaire racehorse owner Sir Humphrey de Trafford, 4th Baronet,[1] and the Hon. Cynthia Hilda Evelyn Cadogan, a daughter of Henry Cadogan, Viscount Chelsea.[3] The de Trafford Baronets descend from a pre-Conquest-founded line of recusant (a term coined to describe the minority of English people who remained Roman Catholic during and after the English Reformation in a time of religious persecution) lords of the manor who were wealthy in the Middle Ages and restored to hereditary title in the mid-19th century. Ann (later Dame Ann) continued to adhere to the religion of her family, Roman Catholicism.
Ann Parker Bowles was a Commissioner of the Commonwealth Girl Guides Association. For these and other services to the Commonwealth she was invested as Commander of the Order of the British Empire (CBE) in the 1972 New Year Honours, and, five years later, as a Dame Commander of the Royal Victorian Order (DCVO) in 1977.
On 14 February 1939, she married Derek Henry Parker Bowles, son of Eustace Parker Bowles (born Eustace Parker) and Wilma Mary Garnault Bowles, only daughter of Sir Henry Ferryman Bowles, 1st Baronet. They had four children:
Her eldest son Andrew was the first husband of Queen Camilla of the United Kingdom.[3]
