Prince William, like his father King Charles III, is descended from two children of Queen Victoria of the United Kingdom – King Edward VII, through his paternal grandmother Queen Elizabeth II, and Princess Alice, the second daughter and third child of Queen Victoria, through his paternal grandfather Prince Philip, Duke of Edinburgh. Though his mother Diana, Princess of Wales, William is a descendant of both King Charles II of England by two illegitimate sons – Charles Lennox, 1st Duke of Richmond, and Henry FitzRoy, 1st Duke of Grafton – and King Charles II’s brother King James II of England by his illegitimate daughter Henrietta FitzJames.
