In 1916 his younger daughter, Nadejda ("Nada") married Prince George of Battenberg, older son of Prince Louis by Queen Victoria's granddaughter, Princess Victoria of Hesse-Darmstadt. The Battenberg family was itself the product of a morganatic marriage, but one whose members had been allowed to use the style "His/Her Serene Highness". A year after Nadeja and George's wedding, however, the English branches of the Battenberg family gave up their princely title, and Prince George, who was eventually to become 2nd Marquess of Milford Haven, took the surname Mountbatten and bore the courtesy title of earl, his wife becoming known as Countess of Medina.
