_. The Lord Mowbray, Segrave and Stourton died 7 January, 2021, aged 67 following a fall at his Yorkshire home.
His peerages are three of the oldest on the Roll of the House of Lords. He was the 27th Baron Mowbray [created by Writ of Summons in 1283], 28th Baron Segrave [created by Writ of Summons, 24 June, 1295], and 24th Baron Stourton [created by Letters Patent, 13 May, 1448].
The Lords Mowbray, Segrave and Stourton claimed unsuccessfully in 1912 the ancient Earldom of Norfolk  to which he was the senior co-heir. The Norfolk earldom had originally been bestowed on the Bigod family. Roger Bigod surrendered the earldom to the King in 1302 and ten years later it had been regranted to Thomas of Brotherton, and the success of this claim depended on the validity of the surrender, as it was the regranted peerage which was under claim. He failed in his case, as it was held (in 1906) that the surrender of 1302 was invalid, and, as "The Complete Peerage" states: "the decision in the case involved a denial of the existence of the earldom in Thomas of Brotherton and his issue." The barony of Stourton which was created by patent in 1448, has existed continuously in the male line since that date. The baronies of Mowbray and Segrave were a different case. The first Lord Mowbray received a writ of summons to Shrewsbury in 1283 and other later summonses to undoubted Parliaments. The first Lord Segrave was also at Shrewsbury, but was also summoned to Parliament in 1295. The daughter of the 4th Lord Segrave married the fourth Lord Mowbray, and the titles since then have been held together. The baronies came through the Mowbrays, Dukes of Norfolk, to the Howards, Dukes of Norfolk, and so to 1777, when they fell into abeyance between the two daughters of Philip Howard, brother of the 9th Duke of Norfolk. One married the 16th Lord Stourton and the other the 9th Lord Petre. In 1877 the 20th Lord Stourton applied for the termination of the abeyance, and the case was decided in his favour.
He was also senior co-heir to the entire moiety of the Baronies of Strange de Blackmere, Talbot, and Howard, and senior co-heir to the baronies of Braose of Gower, Greystock, Dacre of Gillesland, Ferrers of Wemme, Verdon, Darcy of Darcey, and Giffard of Brimmesfield, &c. The family claimed, as Lord Mowbray, the premier barony of England.
The peer was head of the family which runs the annual Allerton Park Horse Trials at Knaresborough. The event, now into its third decade, typically attracts more than 500 riders from the four higher levels of national eventing, as well as around 2,500 visitors.
Edward Stourton was born 17 April 1953, the eldest son of Charles, Lord Mowbray, Segrave and Stourton, CBE [1923-2006], and his first wife the Hon Jane Faith de Yarburgh-Bateson [1933-98], daughter of the 5th Baron Deramore. His father – a Wodehousian figure, was head of one of the oldest Roman Catholic families in the country.
Educated at Ampleforth College in North Yorkshire, he succeeded to his father's peerages, 12 December, 2006.
He gained control of the family estate on his 30th birthday in 1983, and soon afterwards sold Allerton Castle, the family’s 19th century Gothic house, to an American businessman, whose foundation renovated it. The castle now forms an impressive backdrop to the lakeside eventing venue.
He married, 12 July, 1980, Penelope (Nell) Lucy Brunet, daughter of Dr Peter Cameron Jamieson Brunet, of Oxford. Lady Mowbray, Segrave & Stourton survives him, with their five children, a son, James, and four daughters, the Hon Sarah Louise [born 1982], the Hon Isabel Laura [born 1983], the Hon Camilla Charlotte [born 1987], and the Hon Francesca Jane [born 1988].
Prince William with Miss Catherine Middleton, Prince Harry, and Princess Beatrice of York attended the marriage which took place, 8 January, 2011, at Aldborough, North Yorkshire, between Harry Buchanan Aubrey-Fletcher (b 1982) scion of the Aubrey-Fletcher Baronets, 3rd son of Sir Henry Aubrey-Fletcher, 8th Baronet, and Lady Aubrey-Fletcher, of Buckinghamshire, & the Hon (Sarah) Louise Stourton (b 1982), eldest daughter of the 27th Baron Mowbray (28th) Baron Segrave & 24th Baron Stourton (b 17 Apr 1953), of Allerton Park, near Harrogate, North Yorkshire, and the Baroness Mowbray, Segrave & Stourton, &c.
The ancient peerages now devolve upon his only son, the Hon James Charles Peter Stourton, who was born 12 December, 1991.
