Obscure arms, Grey usually bore the well known arms of <i>Barry of six argent and azure</i>, as did one of the junior branches Grey of Groby. This is possibly a reference to the arms of de Quincy (<i>Gules, seven mascles or 3,3,1</i>), later adopted by Ferrers of Groby. The single listing for this version of Grey in Burke's General Armory does not indicate genealogy or seat.
<p>Sir John Grey, of Groby, Leicestershire (c. 1432[1] – 17 February 1461) was a Lancastrian knight, the first husband of Elizabeth Woodville who later married King Edward IV of England, and great-great-grandfather of Lady Jane Grey. He was the son and heir of Elizabeth Ferrers, 6th Baroness Ferrers of Groby (1419–1483) and of Sir Edward Grey (c. 1415–1457), a son of Reginald Grey, 3rd Baron Grey de Ruthyn.[1][2] His father was summoned to parliament as Baron Ferrers of Groby in right of his wife.[1][3] After the death of Grey's father his stepfather, John Bourchier, assumed his wife's title, Baron Ferrers of Groby
