Elizabeth II has a younger sister. Princess Margaret (August 21, 193-February 9, 22) was the wife of Count Snowden, the second daughter of King George VI and Elizabeth Bowes-Lyon, and the only sister of Queen Elizabeth II. As a princess, Margaret did not have the title and pressure of the first heir of her sister Elizabeth II, but she was inseparable from her sister Elizabeth II since she was a child. They were educated and trained by the royal family.
