Grosvenor (/ˈɡroʊvənər/) is a surname derived from Hugh Le Grand Veneur, a member of a Norman French family that aided William the Conqueror in 1066. "Le Grand Veneur" literally means "the Master Huntsman" in French, an elevated title in William's 11th century French court. Initially, Hugh was called Hugh Lupus. Lupus was portly, and his townsmen gradually changed the appellation from "Le Grand Veneur", "the Master Huntsman," to "Le Gros Veneur", "the Fat Huntsman", and Hugh wore the epithet with pride.
