Queen Elizabeth II's family tree contains a lot of people and as members of the family have children, the family tree quickly grows. After Queen Elizabeth II, the longest-reigning monarch in British history died on Sept. 8, 2022, her oldest son Charles became the king and his wife, Camilla, became the queen consort. The next in the line of succession is King Charles III's oldest son, Prince William. Even though those members of the royal family are part of the immediate line of succession, there are a lot of other people in Queen Elizabeth II's family tree.

Queen Elizabeth II is the oldest daughter of King George VI and Queen Elizabeth. They had one other daughter named Princess Margaret. Princess Margaret died in February 2002 and the Queen mother died in March of the same year.

Queen Elizabeth II became the queen after the passing of her father, King George VI when she was 25 years old. Queen Elizabeth II married Philip, Duke of Edinburgh on Nov. 20, 1947. Prince Philip died on April 9, 2021, and Queen Elizabeth II died on Sept. 8, 2022. Queen Elizabeth II reigned for 70 years, making her the longest reigning British monarch to date.

Queen Elizabeth II and Prince Philip had four children together: King Charles III, Anne, Princess Royal, Andrew, Duke of York and Edward, Earl of Wessex.

King Charles III was first given the title Prince Charles of Edinburgh, then Duke of Cornwall, Duke of Rothesay, Prince of Wales and now holds his current title, King Charles III. King Charles III was married twice. He was first married to the late Diana, Princess of Wales, who tragically passed in a car accident in 1997. He then married Queen Consort Camilla Parker Bowles in 2005. Since King Charles III was the eldest son of the previous reigning monarch Queen Elizabeth II, he was next in the line of succession following her death. 

Anne, Princess Royal was also married twice, first to Capt. Mark Phillips in 1973 and then to Vice-Admiral Timothy Laurence in 1992. 

Andrew, Duke of York was married to Sarah, Duchess of York, but the two divorced in 1996. Prince Andrew took a step back from his royal duties in 2019 due to his involvement with Jeffrey Epstein.

Prince William is married to Catherine, Princess of Wales, who he married at Westminster Abbey in 2011 and Prince Harry is married to Meghan, Duchess of Sussex, who had their wedding in May 2018. Since Prince William is the oldest son of the reigning King Charles III, he is the next in the line of succession.
