One of his older sisters, Princess Karoline of Baden, became the first queen of Bavaria as the consort of King Maximilian I Joseph (she was his second wife, but Bavaria was not yet a kingdom during the lifetime of his first wife, Princess Auguste of Hesse-Darmstadt). Her daughter Amalie became the queen of Saxony as the consort of King Johann. Another daughter, Sophie, became the mother of Emperor Franz Joseph of Austria; the present imperial line of the Habsburgs descends from her. Yet another daughter, Ludovika, married into the ducal branch of the house of Wittelsbach; two of her daughters became queens (Elisabeth of Austria and Marie of the Two Sicilies). Also, members of the present day houses of Hohenzollern-Sigmaringen, Belgium, and Luxembourg descend from her.
Are there other notable connections to the grand duchy of Baden?
