A primary example of the contemporary usage of this style is the Belgian Royal Family. HI&RH Lorenz, Archduke of Austria-Este, Prince of Belgium is a member of the Imperial House of Habsburg-Lorraine by birth, but upon his marriage to HRH Princess Astrid of Belgium, he also became a member of the Belgian Royal Family by marriage.
