The couple is Archduchess Marie-Astrid (older sister of Grand Duke Henri of Luxembourg) and Archduke Carl Christian of Austria. They have five children and 15 grandchildren. A fun fact is that their kids are double second cousins with the children of Princess Astrid and Prince Lorenz of Belgium since Astrid and Marie-Astrid are first cousins through King Leopold III of Belgium (both are named after Queen Astrid) and Lorenz and Carl Christian are first cousins through Emperor Charles I of Austria.
