Isabelle's lineage made her valuable to René of Anjou, who was dealing with a succession crisis over the duchy of Lorraine. He was trying to strengthen ties with Lorraine's nobility which is why her name appears with those of her mother and Yolande, Duchess of Lorraine, in a handwritten collection of poems by Alain Chartier offered to Marie de Clèves.[2] Other than that not much is known about Isabelle's childhood; her marriage negotiations started before she was eighteen and she was raised a catholic. She had one half-sister, Alix de Beauvau, who was legitimized when her father remarried.
