English: Francis, Duke of Teck (1837-1900) member of the German nobility, & later of the British Royal Family, as father of Queen Mary, wife of King George V. As the product of a morganatic marriage, Francis was not acceptable as a husband for princesses in most of the European royal houses. He married Princess Mary Adelaide of Cambridge, daughter of Prince Adolphus, Duke of Cambridge, & a granddaughter of George III. Already in her thirties, Mary Adelaide was also short of choices for marriage.
