Facts and Events
The son of another Roger de Mowbray, and grandson of William de Mowbray, he served in the Welsh and Gascon Wars. He was summoned to the Parliament of Simon de Montfort in 1265, but such summonses have later been declared void. However, in 1283 he was summoned to Parliament by King Edward I as Lord Mowbray.
De Mowbray married Rose, a daughter of Richard de Clare, 6th Earl of Gloucester. They had at least two children:
Roger was born about 1257 and in 1278 (6EdwardI) he had livery of his lands. In1282 and 1283 he was summoned for military service against the Welsh. They had revolted against the Marcher Lords, who killed their leader, Llewellyn, at Ironbridge, Shropshire. In June 1283 Roger was at the Parliament at Shrewsbury and again in 1287 the King required his presence at a military council at Gloucester.
In 1291 he was called into military service against the Scots, and again in 1296. There had been a Parliament with the Scots at Norham in the former year, and in the latter there was a savage sacking of Berwick with Earl Warrenne being made ruler of Scotland and the Stone of Scone removed to London.
From 1278 to 1294 there were quo warrento enquiries challenging the jurisdictional rights of the magnates. Perhaps it was as an outcome of these that in 1295 Roger was created Lord Mowbray, Baron by Writ. As no previous barony had been created by writ, he became premier baron of England.
In 1294 there was an outbreak of war with France when Philip IV confiscated Gascony. In September 1294 Roger was going there on the King's services. In 1297 Roger again attended Parliament, this time at Salisbury. A record from 1295 shows 53 magnates summoned to Parliament
There is a record of Walter de Burnham agreeing to serve in Flanders under Roger de Mowbray in 1297. In that year and Edward I left for Flanders, and England was on the verge of civil war. Roger died at Ghent in 1297 and his body was brought back to be re-interred in Fountains Abbey where there is effigy in stone.
His marriage to Rose de Clare, daughter of the Duke of Gloucester, had been arranged as early as his 13th. birthday by his and Rose's mothers. It took place in 1270 and produced a son and heir, John and perhaps a second son Geoffrey.
The entry in Burke's Extinct Peerage makes reference to a son Alexander who went to Scotland, but in the Mowbray Journal, Stephen Goslin claims that Alexander was in fact one of the seven sons of Geoffrey de Mowbray of Scotland, descended from Philip de Mowbray.
