When, at 2.40am on 21 April 1926, the first child of the Duke and Duchess of York was born by Caesarean section at 17 Bruton Street in London’s Mayfair, nobody expected her to become Queen. The Princess's arrival was not a big cause for celebration, she was third in line to the throne, behind her father, who was not expected to become King.
The little girl was named Elizabeth Alexandra Mary after her mother, who was born Elizabeth Bowes-Lyon. Her middle names were a tribute to her grandmother Queen Mary and her great-grandmother Queen Alexandra.
Elizabeth's uncle – known as David in the family – ascended to the throne as Edward VIII after the death of her grandfather George V. However, in 1936, Edward abdicated to marry American socialite Wallis Simpson, having reigned for less than a year. Suddenly, Princess Elizabeth's life changed forever.
