[Robert Ros] WAS descended from the noble family of Ros or Roos, of Hamlake. His father Everard died when he was thirteen years of age, and he had livery of his lands from the wardship of the Crown in the second year of the reign of Richard I. on payment of a hne of one thousand marks; which shows that his possessions must have been very large.

He was one of the Barons who leagued together to obtain the Great and the Forest Charter from John; and when that King had signed them at Runnemede, he was one of the chief persons who undertook to constrain him to observe them^a He married Isabella, the daughter of William the Lion, King of Scotland, by whom he had two sons, William and Robert. He gave the first his castle of Helmesley [Map], with the patronage of the monasteries of Kirkham, Rievaulx [Map], and Warden, to the other his castle of Werke and a barony in Scotland, held by knight's service of his brother-in-law. Of both the above-mentioned castles he was the founder. He confirmed to the Templars his manor of Ribstone, with other possessions, assumed the habit of their order, died in 1231, and was buried in the Temple church [Map]. The effigy of Ros is cross-legged, and his hands raised in the act of prayer; the hood of his hauberk is thrown back to show his visage. His sword depends from a belt adorned with broad studs; his surcoat reaches to his heels, which are armed with the pryck spur, and rest on a lion. On his shield are three water bougets, which were the bearing of Ros, Argent, in a held Gules. This figure, like that of Robert de Vere, is of a period subsequent to that of the decease of the person whom it is said to represent.
