Prince George, a great-grandchild of Queen Elizabeth II, is third in line to the throne. George's grandfather, Prince Charles, is first, followed by his dad, Prince William. His two younger siblings, 4-year-old Princess Charlotte and 1-year-old Prince Louis, are in line right behind him.
Though George isn't spotted in public as much as the grown-up royals, he was recently seen out with his siblings and his cousin, 6-month-old Archie. George served as a page boy at the wedding for Archie's parents, Prince Harry and Duchess Meghan, last year.
