Question: Who is Blanche Of France, Duchess Of Orléans's maternal grandfather?

Knowledge 1: Blanche of France, Duchess of Orléans
Blanche of France (1 April 1328 – 8 February 1393) was the posthumous daughter of King Charles IV of France and his third wife, Jeanne d'Évreux.She holds the distinction of being the last direct Capetian; she was the last-surviving member of her family, and her marriage to her cousinPhilippe d'Orléans proved childless.With Blanche's death in 1393, the House of Capet continued to exist only via its numerous cadet branches. [SEP] Knowledge 2: Jeanne d'Évreux
Jeanne d'Évreux (1310 – 4 March 1371) was Queen of France and Navarre as the third wife of King Charles IV of France.She was the daughter of his uncle Louis, Count of Évreux and Margaret of Artois.Their lack of sons caused the end of the direct line of the Capetian dynasty.Because she was his first cousin, the couple required papal permission to marry from Pope John XXII.They had three daughters, Jeanne, Marie and Blanche.Jeanne died on 4 March 1371 in her château at Brie-Comte-Robert, in the Île-de-France region, some twenty miles southeast of Paris.She was buried at the Basilica of St Denis, the necropolis of the Kings of France.Two of Jeanne's remarkable possessions survive:her book of hours and a statue of the Virgin and Child.The "Book of Hours", known as the " Hours of Jeanne d'Evreux," is in The Cloisters collection of the Metropolitan Museum of Art in New York.It was commissioned from the artist Jean Pucelle between 1324 and 1328, probably as a gift from her husband.The book contains the usual prayers of the canonical hours as arranged for the laity along with the notable inclusion of the office dedicated to St Louis, her great-grandfather.The small statue of the Virgin and Child (gilded silver and enamel, 69 cm high), which Jeanne left to the monastery of St Denis outside Paris, is in the Louvre Museum.
