'Gros' means fat. Gilbert's uncle, Hugh Lupus, was, we know, a fat man; in fact, he was nicknamed 'Hugh the Fat.' The Grosvenors of that period probably inherited obesity from their relative, Hugh Lupus, therefore, and the fable that they were called Grosvenor on account of their office of 'Great Huntsman' to the Dukes of Normandy is not to be relied on.
"We are further on told by the old family historians that when Sir Robert Grosvenor lost the day in that ever-memorable controversy with Sir Richard le Scrope, Baron of Bolton, concerning the coat of arms—'Azure, a bend or'—borne by both families, Sir Robert Grosvenor took for his arms one of the garbs of his kinsman, the Earl of Chester.
"It did not seem to occur to these worthies that the Earl of Chester, who was their ancestor's uncle, never bore the garbs in his arms, but a wolf's head.
"It is true that one or two subsequent Earls of Chester bore garbs, but these Earls were far too distantly connected with the Grosvenors to render it likely that the latter would borrow their new arms from this source.
"It is curious that there should have been in this same county of Chester a family of almost identical name also bearing a garb in their arms, though their garb was surrounded by three bezants.
"The name of this family was Grasvenor, or Gravenor, and, moreover, the tinctures of their arms were identical with those of Grosvenor. It is far more likely, therefore, that the coat assumed by Sir Robert after the adverse decision of the Court of Chivalry was taken from that of Grasvenor, or Gravenor, and that the two families were known at that time to be of common origin, although their connection with each other has subsequently been lost.
"In French both gros and gras mean fat, and we have both forms in Grosvenor and Grasvenor.
"A chief huntsman to Royalty would have been Grandvenor, not Grosvenor or Grasvenor.
"All these criticisms of mine, however, only affect the origin of the arms, and not the ancient and almost Royal descent of this illustrious race. Hugh Lupus, Earl of Chester, was a son of the Duke of Brittany, as is plainly stated in his epitaph.
"This connection of uncle and nephew, then, between 'Hugh the Fat' and Gilbert Grosvenor implies a maternal descent from the Dukes of Brittany for the first ancestor of the Grosvenor family.
"In virtue of their descent from an heiress of the house of Grosvenor, it is only necessary to add the Tauntons of Oxford are Grosvenors, heraldically speaking, and that quartering so many ancient coats through
