Member of Parliment 1261, 1265, summoned to Parliament in 1264 as Baron Ros of Belvoir Castle. In 1258 he was apointed chief commissioner of Herfordshire to inquire into excesses there. In that same year he was summoned for service against the Welsh and the Scots. He sided with Simon de Montfort in 1264/4 and was holding Northampton under the younger Simon when the King took it.

He was summoned to Monfort's parliament; but these writs, issued by Simon in the King's name, are no longer regarded as valid for the creation of peerages. In May 1265 Prince Edward (King Edward I) escaped from his custody at Hereford to Wigmore Castle, with help of Roger de Mortimer. Robert later surrendered Gloucester Castle to the Prince. After Montfort was slain and his rebellion quashed at the Battle of Eversham Robert received a full pardon at the insistance of Prince Edward.

In 1276 he was one of the magnates, who, in council at Westminster, gave judgement against Llewelyn, and was summoned for service in the consequent campaign. By his marriage he became Lord of Belvoir.

  7.   Helmsley Castle, p. 24-5.

    Son of Peter de Roos, he received Helmsley Castle as his inheritance. William seems to have been content to occupy Helmsley Castle from 1227-58 without much altering his father's buildings, though he did build a new chapel which was consecrated in 1246. This replaced a chapel in the east tower.
    William's son, another Robert de Roos, began to update the castle in the third quarter of the 13th century.
