テック公
Francis, Duke of Teck (Francis Paul Charles Louis Alexander; 28 August 1837 – 21 January 1900), known as Count Francis von Hohenstein until 1863, was an Austrian-born nobleman who married into the British royal family. He was the father of Queen Mary, and thus a great-grandfather of the current British monarch, Queen Elizabeth II. Francis held the Austrian title of Count of Hohenstein ("Graf von Hohenstein"), and the German titles of Prince ("Fürst") and later Duke of Teck ("Herzog von Teck"), and was given the style of Serene Highness in 1863. He was granted the British style of Highness in 1887.
