Nicknamed Furfan, Robert de Ros, as a minor at his father's death was the ward of the King in 1185, when his lands were in the custody of Ranulph de Glanville. In 1190 he had livery of the lands of his Trussebut inheritance. He served as Sheriff of Cumberland 1213-15. As the son-in-law of William the Lion, King of Scotland, he was of his escort into England November 1200, to do homage. He was loyal and closely associated to King John, but was one of his most vigorous opponents in the matter of Magna Carta, being one of the 25 elected to see its provisions were obeyed. He was a benefactor of Rievaulx and Kirkham, and of the Templars, and also founded a hospital for the lepers in Northumberland. His date of death is not known, but his son and heir, William de Ros, did homage for his father's lands 23 December 1226, so whether he had died by this time, or as some speculate, as a Templar, had retired from secular life, is not known.
