 Seven years after her death, her husband took as his second wife, Isabelle, the daughter of John I, Duke of Lorraine and Sophie of Württemberg.Molly Costain Haycraft's fictionalized account of Isabella's life and courtship with her husband, "The Lady Royal", recounts several incidents in the lives of the princess and other members of Edward III's family, but contains a number of historical errors.Chief among these is the explanation of the book's title; according to the story, Isabella (or Isabel, as she is identified in the story) was titled Princess Royal and later promoted to "Lady Royal" by her parents.
