Princess Margaret, Countess of Snowdon, was the only sibling of Queen Elizabeth II and the younger daughter of King George VI and Queen Elizabeth.  She was born on August 21, 1930. When she was 6 years old her Uncle Edward VIII was abdicated, and her father Prince Albert became King George VI, then Princess Elizabeth became first in line and Margaret came in second.

Their Scottish governess ,Marion Crawford, described Elizabeth as been the sensible one and Margaret as being full of fun and spoiled by her parents. In 1947, she made her first foreign trip abroad when she joined her parents and sister on a three-month tour of South Africa. They were accompanied by the King’s equerry Captain Peter Townsend. Later that year, she was a bridesmaid at her sister’s wedding to Prince Philip.
