Maria Teresa d'Austria d'Este (1859-1919), last queen of Bavaria. Daughter, only child, of Archduke Ferdinand of Austria-Este and his wife, Archduchess Elisabeth of Austria. Spouse of Ludwig III, last king of Bavaria, with whom she had 13 children. Oddities: She was Jacobite heir-general to the throne of Great Britain, and as a descendant of Electress Sophia of Britain born before 1948, under the Sophia Naturalization Act of 1705, could have claimed British citizenship.
