Urbino, were bestowed upon her younger son, Francesco Maria de' Medici. Marriage of Gian Gastone Cosimo became perturbed by the question of the Tuscan Succession following the death of his mother. Ferdinando was lacking any children, as was Anna Maria Luisa. The latter, who was high in her father's estimation, put forward a German princess to marry Gian Gastone. The lady in question, Anna Maria Franziska of Saxe-Lauenburg, nominal heiress of the Duchy of Saxe-Lauenburg, was extremely wealthy. Cosimo once again dreamed of a Medici cadet branch in a foreign land. They were married on 2 July 1697. Gian Gastone and herself did not get along; he eventually abandoned her in 1708.

In an attempt to salvage Gian Gastone from shipwreck, Rinnuci tried to coerce Anna Maria Franziska to return to Florence, where Gian Gastone longed to be. She blankly refused. Her confessor, hoping to keep her in Bohemia, regaled her with tales of the "poisoned" Eleanor of Toledo and
