Royals Why Meghan Markle's Birthday Has Extra Special Meaning for the Queen Meghan Markle shares her birthday with another important royal family member By Maura Hohman Published on July 31, 2018 09:33 AM Share Tweet Pin Email Meghan Markle‘s 37th birthday on August 4 is a big day for the royal family. Not only does it mark Meghan’s first official birthday as the Duchess of Sussex, it’s also the birthday of another important royal: the late Queen Mum, Queen Elizabeth‘s beloved mother. The Queen Mum, born Elizabeth Angela Marguerite Bowes-Lyon on August 4, 1900, was an important member of the royal family. One of nine children, she was intelligent and well-educated, and spoke French fluently by age 10 after receiving home-schooling lessons, according to the royal family’s official website. She met her husband, then Prince Albert, in her late teens and they married in 1923. The couple’s first daughter, Princess Elizabeth was born in 1926, and their second, Princess Margaret, in 1930. The Queen Mum and her husband unexpectedly claimed the throne (following the abdication of Prince Edward over his marriage to American divorcée Wallis Simpson) in 1937, and she immediately made it the central duty of her and her family.

I shall not leave unless their father does, and the King will not leave the country in any circumstances whatsoever.” Popperfoto/Getty As a new mother, the Queen Mum was attached to baby Elizabeth and spoke openly about how hard it was to leave her to fulfill her royal duties. When she and Albert had to travel to Australia in 1927, she wrote in her diary that she felt “very miserable at leaving the baby,” according to the biography, The Queen Mother. Time Life Pictures/Getty When her husband died in 1952, many thought the Queen Mum would become a recluse since she was so devoted to her husband — but she stayed active because of her obligations to her family and the people. She was also especially close with her grandson Prince Charles. Tim Graham/Getty The Queen Mum also cared deeply about her great-grandchildren. According to The Guardian, she placed £19 million in trusts for them to be passed on after she died in March 2002. She left the bulk of her estate, between £50 and £70 million to Queen Elizabeth.
