Henry was born on 8 April 1914 in
Belgravia, London. She was descended from Prime Ministers
John Russell (her great-great-grandfather) and
Robert Peel, and was the
cousin once removed of
Bertrand Russell. She was raised by grandparents in Ireland after her parents separated. After returning to England and finishing her education, she made her
society début in 1932. She had a twin sister, who died at the age of 21. In 1938 she married army officer Donald Standage; the couple had one daughter. The marriage broke down in the late 1940s and they were divorced by 1950. After getting into debt through gambling, Henry accepted a forged cheque from a friend as a loan. She was convicted at the
Old Bailey in 1951 and sentenced to 12 months imprisonment; though the
Daily Telegraph's obituary claims "...she was naïve enough not to realise that the cheque had been forged". At the latter, she came under the care of Anglo-Irish prison reformer
Mary Size, who she later described in her 1952 book
Who Lie in Gaol as "a mixture of discipline and humanity." ==Career==
