The royal family cheat sheet you need in your life

While the world is so familiar with Prince George and Princess Charlotte, many are not as familiar with the other great-grandchildren. Prince William and Kate have two children: Prince George, who is third in line of succession to the British throne; and his younger sister, Princess Charlotte, fourth in line to the throne. Once Kate's third child is born, he or she will be fifth in line. Which then puts Prince Harry down to sixth in line.
