The royal family has had quite an injection of ordinary blood, since the 18th and 18th centuries of marriage almost exclusively with German princes and princesses. Queen Alexandra was Danish, Queen Mary German, the Queen Mother Scottish, Diana English as is Catherine. Most of the wider royal family have married into the middle classes. Prince Philip was ostensibly Greek, the Duchess of Gloucester Danish (?), Princess Michael Austrian (?) and of course Harry's wife American. Very few from European royal houses which is good as so many were descended from Queen Victoria.
