He died on 20 September 1777, aged 91, without a male heir, when several of his titles (the Dukedom of Norfolk, the
Earldoms of Norfolk, Arundel and Surrey, and the Barony of Maltravers) passed to his second cousin (whom he hardly knew)
Charles Howard, 10th Duke of Norfolk, a grandson of Charles Howard of Greystoke, Cumberland, a brother of the 6th Duke. The Earldom of Norwich and Barony of Howard of Castle Rising, which were created for his grandfather, the 6th Duke of Norfolk, became extinct. Finally, several old English baronies created by writ including
Baron Mowbray,
Baron Segrave Baron Howard, Braose of Gower, Greystock, Ferrers of Wemme,
Baron Talbot, Strange of Blackmere, Furnivall and Giffard of Brimmesfield, fell into abeyance among the two daughters of his younger brother Philip Howard (1688-1750) of
Buckenham Tofts in Norfolk. Most of these passed via Philip's eldest daughter Winifred Howard (1726-1753), who married
William Stourton, 16th Baron Stourton (1704–1781). ==References==
