It was said that Walter, William's maternal uncle, was occasionally forced to hide the young duke in the houses of peasants, although this story may be an embellishment by Orderic Vitalis.
Det blev fortalt, at Walter, Vilhelms onkel på sin mors side, til tider var tvunget til at skjule den unge hertug i bøndernes huse, selvom denne historie muligvis kan være noget, som Orderic Vitalis har fundet på.
