。
玛格丽特（Margaret）是母亲在格拉米斯城堡（Glamis Castle）的家庭所在地出生的大约300年以来第一位王室成员。她的教育受到母亲的监督，她和姐姐被托付给一位女教师。玛格丽特对音乐表现出了早期的兴趣，并从四岁开始上钢琴课。当叔叔爱德华八世国王退位时，她才六岁，父亲成为国王。此后，作为王位继承人的伊丽莎白公主接受了单独的教育，而玛格丽特则继续在母亲的监督下。此外，她还必须参加公共活动。
Margaret, who became known for her glamour and beauty, displayed an early love for nightlife and the arts. When she was in her early 20s, she fell in love with Group Capt. Peter Townsend, a war hero who had served as an equerry to her father. Their romance became public knowledge when Margaret was seen brushing lint off Townsend’s jacket at her sister’s coronation in 1953. Although Townsend and Margaret wished to marry, the fact that he was divorced made the marriage unsuitable, and Margaret gained worldwide sympathy in 1955 when she publicly renounced their plans to wed.
Margaret was already a fixture on London’s social and arts scene when she began secretly seeing photographer Antony Armstrong-Jones in 1958. The announcement of their engagement in February 1960 caught many by surprise. They were married on May 6, 1960, in the first royal wedding to be televised. (Armstrong-Jones was created earl of Snowdon in 1961.) The marriage was at first successful, and they had two children: David, Viscount Linley, born in 1961, and Lady Sarah, born in 1964. By the 1970s, however, the couple had grown apart. Both of the Snowdons engaged in public love affairs, and the princess scandalized conservative monarchists, cultivating friendships and romances among actors, writers, ballet dancers, and artists. She spent much of her time on the Caribbean island of Mustique, in the Grenadines. When her long-standing affair with Roddy Llewellyn, a landscape gardener 17 years her junior, was exposed in 1976, she lost public sympathy, and her volatile marriage finally ended in 1978, the first divorce in the British royal family in 400 years.
Eventually her extensive charitable work, combined with a new, more modern sympathy for the restricted options she faced, gained her a measure of public respect. Princess Margaret, who smoked and drank heavily throughout her adult life, was often in ill health. She had surgery for possible lung cancer in 1985 (the tissue proved to be benign) and later suffered a series of strokes.
