Queen Elizabeth II was the ultimate matriarch whose extended family meant the world to her.The first of her and Prince Philip’s four children, Charles, was born at Buckingham Palace in November 1948 when she was a 22-year-old princess and four years before she became Queen. News of the prince’s birth was broken with a traditional notice pinned to the railings outside the palace, where waiting crowds burst into a rendition of For He’s A Jolly Good Fellow.The water in the Trafalgar Square fountains was dyed blue to celebrate his arrival.The princess appeared to adapt to motherhood quickly, although two weeks after her firstborn came along, she wrote in her diary, “I still find it hard to believe that I really have a baby of my own.” The couple’s daughter Princess Anne was born at Clarence House in August 1950, and Elizabeth wrote in a letter that Charles treated his new baby sister “with great care”.
