ROGERL DE QUINCY, Earl of Winchester, died without male issue 25 April 1264, and was probably buried at Brackley, Leicestershire, his Earldom reverting to the Crown.
He married first HELEN OF GALLOWAY, second but first surviving daughter and coheir of Alan, Lord of Galloway, Constable of Scotland, who died in 1234. Helen died after 21 Nov. 1245 and was buried at Brackley. He married second, before 5 June 1250, Maud de Bohun, widow of Anselm Marshal, Earl of Pembroke, who died in Dec. 1245, and daughter of Humphrey de Bohun, by Maud, daughter of Raoul (Ralph) de Lusignan, Count of Eu. The younger Maud was not very old when she died without issue in Grosby, Leicestershire, 20 Oct. 1252 and was buried at Brackley. He married third, without license, before 5 Dec. 1252, Eleanor (or Alianole) de Ferrers, widow of William de Vaux (who had died without issue shortly before 14 Sept. 1252), and seventh daughter of William de Ferrers, 5th Earl of Derby, by his first wife, Sybil (of whom Eleanor was coheir). His widow was assigned dower 21 Sept. 1264, and married third, before 8 Sept. 1267, as his second wife, Roger de Leyburn, who died about Oct. 1271. She died shortly before 26 Oct. 1274, and was buried at Leeds Priory.
He was apparently on Crusade at Damietta in the Holy Land when his father died, and inherited his father's lands 16 Feb 1220/1. Upon his mother's death in 1234/5 he was recognized as the Earl of Winchester. He traveled with his mother's knights to Brittany in the spring and summer of 1230.
By rights inherited through his first wife he became hereditary Constable of Scotland in 1234. He needed the help of the Scottish king to quash a rebellion against his tyrannical rule of his lands there in 1247. He had witnessed an agreement between Alexander of Scotland and Henry III on 25 Sept. 1237, served in Gascony in 1242, against the Welsh in 1258, 1260, 1261 and 1263, and was an arbitrator between the King of Scotland and Henry III in 1257/8. He took up arms for Henry Ill in 1260, 1261 and 1263.
