From Royal Tombs: "William of Windsor was the eleventh child of Edward III and Philippa of Hainault, and Blanche of the Tower (d. 1342) was the eighth; both dying in infancy. Their joint tomb now stands in St. Edmund's Chapel, Westminster, beside that of another prince, John of Eltham. The joint tomb appears to have been executed as late as 1376 when John Orchard was paid for supplying 'two images of alabaster placed upon a small marble tomb for an infant son and daughter of the Queen" [5]
