In Turin, Christine Marie died on 27 Dec 1663, and her daughter-in-law Françoise Madeleine died 14 Jan 1664. This left Charles Emmanuel II unmarried and without an heir. Proposals came from Françoise Madeleine's sisters but were rejected. It became clear that Charles Emmanuel II wanted to unite with Marie Jeanne Baptiste, who was a member of his own house. This union was supported by Louis XIV. He did not want Charles Emmanuel II to marry an Archduchess of Austria, for fear of loss of influence in the duchy. Negotiations took over a year before Marie Jeanne Baptiste went to Annecy with her grandmother Françoise of Lorraine on 1 May 1665 to meet her future husband. Marie Jeanne Baptiste married Charles Emmanuel II on 20 May 1665 at the Castello del Valentino amid great celebration. Her large dowry included border provinces of Genevois, Faucigny as well as Beaufort which would become the property of the mainline House of Savoy.
