King Charles III is more than just the country's monarch to his younger siblings Princess Anne, Prince Andrew and Prince Edward. Charles is the firstborn of the late Queen Elizabeth II and Prince Philip. Shortly after welcoming Charles in November 1948, the couple expanded their family with Anne in August 1950. Following the death of her father, George VI, in 1952, Elizabeth ascended to the throne at age 25. During her reign, she welcomed sons Andrew and Edward in February 1960 and March 1964, respectively. While the foursome vary in age, they share a strong bond.
