カルロ・エマヌエーレ3世
In 1736 her brother the Duke of Lorraine married the Archduchess Maria Theresa of Austria, daughter and heiress apparent of Charles VI, Holy Roman Emperor. The union between the House of Lorraine and the House of Habsburg allowed a more prestigious marriage for the unwed princess. The already twice widowed Charles Emmanuel III of Sardinia asked for her hand in late 1736.
