Grosvenor was derived from the French title "Le Grand Veneur," meaning "the Master Huntsman." In particular, it refers to Hugh d'Avranches, also known as Hugh Lupus, an Earl of Chester who reigned during the time of William the Conquerer. Hugh was given the official title Hugh Le Grand Veneur, but the townspeople called his Le Gros Veneur, "the fat huntsman," due to his large size.
