Grosvenor History, Family Crest & Coats of Arms
The ancestors of the Grosvenor family migrated to England following the Norman Conquest of 1066. The surname Grosvenor is for a person in charge of hunting on the Lord's estates. Further research showed the name was derived from the Anglo Norman French gros, which means great, or chief, and veneor, which means hunter, collectively "the chief or royal huntsman."  
"This noble house [Westminster] traces its descent in the male line to a family which is stated to have flourished in Normandy for a century and a half before the conquest of England, and obtained its surname from having held the high and powerful office, in that principality, of le Grovenour." 
Another source gives more details: "Le Gros Veneut- 'the great or chief hunter' - that office having been hereditary in the family under the dukes of Normandy. The family descend from an uncle of Rollo the founder of Normandy; and the first settler in England was Gilbert le Grosvenor, nephew of Hugh Lupus, earl of Chester, who was nephew of the Conqueror. This illustrious name is properly Latinized Magnus Venator, but sometimes, absurdly, De Grosso Venatore." 
"The ancient seat of the Le Venours appears to have been Venables, near Evreux. Three brothers of this family came to England with Hugh Lupus: 1. Gislebert Venator, or De Venables, ancestor of the barons of Kinderton, of whom Gislebert Venables of Cheshire is mentioned in Normandy 1180 as 'Gislebert Venator' (Magni Rotuli Scaccarii Normanniae). The French line of Le Venur, descended from him." 
Sir Robert Grosvenor (d. 1396), the English knight, was the "defendant in the case of Scrope and Grosvenor, having descended from Gilbert le Grosvenor, nephew of Hugh Lupus, earl of Chester, in the time of William I. Sixth in descent from Gilbert was Sir Ralph Grosvenor of Hulme, Cheshire, who died in or before 1357, leaving his son Robert under age. "

Grosvenor Spelling Variations

Sound was what guided spelling in the Middle Ages, so one person's name was often recorded under several variations during a single lifetime. Spelling variations were common, even among the names of the most literate people. Known variations of the Grosvenor family name include Grosvenor, Grosvener and others.

To escape the political and religious chaos of this era, thousands of English families began to migrate to the New World in search of land and freedom from religious and political persecution. The passage was expensive and the ships were dark, crowded, and unsafe; however, those who made the voyage safely were encountered opportunities that were not available to them in their homeland. Many of the families that reached the New World at this time went on to make important contributions to the emerging nations of the United States and Canada. Research into various historical records has revealed some of first members of the Grosvenor family to immigrate North America:

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Virtus, non stemma
Motto Translation: Virtue, not pedigree.
