Princess Margaret, the younger sister of future Br

LONDON, UNITED KINGDOM: Princess Margaret, the younger sister of future Britain's Queen Elizabeth II, and her husband the photographer Antony Armstrong-Jones arrive in 1960 in London in the Opera House. Armstrong-Jones was later created Earl of Snowdon. They had two children, son Linley, and daughter Sarah, but announced their separation in March 1976. When the marriage was officially ended two years later, Margaret became the first royal to divorce since Henry VIII in the 16th century. (Photo credit should read AFP via Getty Images)
