16 quarters, with Bear and Ragged Staff badge of Earls of Warwick as crest (his brother was John Dudley, 2nd Earl of Warwick):

• 1: Arms of Dudley (Duke of Northumberland): Or, a lion rampant double-queued vert (Sutton (ancient) (Burke, Sir Bernard, The General Armory, London, 1884, p.987)).
• 2: Arms of Beaumont, Earl of Leicester: Gules, a cinquefoil ermine
• 3: Arms of Somery, feudal barons of Dudley, Worcestershire and Barons by writ of Dudley Castle: Or, two lions passant in pale azure. The de Sutton family inherited Dudley Castle by marriage to Margaret de Somery, daughter of Roger de Somery. These arms of Somery were borne in 1st and 4th quarters by by w:John Sutton, 1st Baron Dudley (1400-1487), KG, whose second son Sir John Dudley, of Atherington, adopted the surname "Dudley" in lieu of his patronymic, and was the father of Edmund Dudley (minister of King Henry VII), whose son was John Dudley, 1st Duke of Northumberland, father of Robert Dudley, 1st Earl of Leicester, who in one portrait bears these arms of Somery in the first quarter, omitting entirely the usual arms of Dudley (Or, a lion rampant double-queued vert ("Sutton (ancient)"))
• 4: Argent, a cross flory azure (unknown), as borne in 2nd & 3rd quarters by by w:John Sutton, 1st Baron Dudley (1400-1487), KG.
• 5: Arms of Woodville/Wydeville: Argent, a fesse and a canton conjoined gules
• 6: Azure, three bars gemelle or in chief a lion passant of the last (otherwise: Barry of twelve or and azure, on a chief of the second a lion passant of the first) (Tregoz / Tregose ? usually given with two bars gemelle, Burke, 1884, p.1026). John de Tregoz, 1st Baron Tregoz (d.1300), of Ewyas Harold, Herefordshire, feudal baron of Ewyas Harold (Sanders, I.J. English Baronies: A Study of their Origin and Descent 1086-1327, Oxford, 1960, p.43), married (in 1245) Juliane de Cantilupe, a daughter of William de Cantilupe (d.1251) and Millicent de Gurnay. He was created Baron Tregoz, by writ of summons to Parliament dated 1297 (Cokayne, G. E. & Geoffrey H. White, eds. (1959). The Complete Peerage, or a history of the House of Lords and all its members from the earliest times, volume XII part 2: Tracton to Zouche. 12.2 (2nd ed.). London: The St. Catherine Press, pp.16-22). He died without male issue, when the title went into abeyance between his two daughters and co-heiresses, the eldest of whom, Clarice de Tregoz, married Roger de la Warre, 1st Baron de la Warre. Her son John de la Warre, 2nd Baron de la Warre, inherited as his share the manor of Ewyas Harold (Complete Peerage, p.22, note (e); Burke, 1884, p.1026). De la Warr is quartered here as no 12, thus not in the expected order. Arms of Tregoz of Ewyas Harold usually given with field "or" or "gules", although Baron Tregoz of Goring, Sussex (created 1304) (probably related) bore the arms with field azure, as shown here.
• 7: Or, a cross azure
• 8: Or, on a chief gules three lions rampant in fess of the field

• 14: Cantilupe (of Hempston Cantelow) arms (a West heiress)
• 15: Gules, three bends enhanced or
