who, during the reign of HENRY II, paid a thousand marks of silver to His Majesty for livery of the lands inherited by his mother from her brother, Walter Espec. This Robert was a munificent benefactor to the knights templars.
EVERARD DE ROS, a minor, and in ward to Ranulf de Glanvill, married Rose Trusbut, of Wartre, in Holderness, and had two sons.
This gentleman must have been a very considerable personage at the period in which he lived, for we find him, in 1176, paying the then very large sum of £526 as a fine for his lands, and in four years subsequently £100 more to have possession of those which the Earl of Albemarle held.Mr de Ros died about 1186, and was succeeded by his son,
SIR ROBERT DE ROS, or de Roos, called Furfan, who, in the reign of RICHARD I, paid a thousand marks fine to the crown for livery of his lands.
Soon after which he was deputed, with the Bishop of Durham, and other great men, to escort the King of Scotland into England.
About the fourteenth year of JOHN’s reign, Robert de Ros assumed the habit of a monk, whereupon the custody of all his lands, viz. Wark Castle, Northumberland, with his whole barony, was committed to Philip de Ulcote; but he did not remain long as a recluse.
He wedded Isabella, daughter of WILLIAM The Lion, King of Scotland, and had issue,
WILLIAM, of Helmsley, of whom presently;Having assumed the habit of the Knights Templars, Robert de Ros died in 1227, and was buried at London, at the Temple Church.

His eldest son's eldest son,
ROBERT DE ROS,
taking an active part against the King, was one of the chief barons, who, after the battle of Lewes, in 1264, where HENRY III and his son, Prince Edward, became prisoners, was summoned to the parliament, which was called by the barons in the King's name, as Baron de Ros, in 1264.His lordship espoused Isabel, the great heiress of William d'Aubigny, Lord of Belvoir, in Leicestershire; and dying in 1285, was succeeded by his eldest son,
WILLIAM, 1st Baron, who was an unsuccessful competitor for the crown of Scotland in 1292, through his grandmother Isabella, daughter of William the Lion, King of Scotland.
In 1296, he obtained from EDWARD I a grant of Wark Castle, upon its forfeiture by the treason of his kinsman, Robert de Ros.
His lordship wedded Maud, daughter and co-heir of John de Vaux, and was succeeded, in 1317, by his elder son,
WILLIAM, 2nd Baron, who married Margery, eldest sister and co-heir of Giles, Lord Badlesmere, of Leeds Castle, in Kent.

The barony of Ros lay under the attainder until the complete triumph of the Lancastrians, by the accession of HENRY VII, when the elder son of the late baron,
EDMUND, 10th Baron, obtained an act of parliament, annulling and making entirely void, the act by which his father was attainted, and restoring to him all the estates and honours of the family.
His lordship died in 1508, unmarried, when the barony of de Ros fell into abeyance between his three sisters and co-heirs, which terminated in favour of

ELIZABETH MANNERS, 15th Baroness, who espoused William Cecil, 2nd Earl of Exeter.
Her ladyship died in 1591, and the barony was confirmed to her son and heir,
WILLIAM CECIL, 16th Baron (1590-1618). His lordship died, however, two years later, without male issue (his father, Lord Exeter, still living), when the barony reverted to his cousin,
FRANCIS MANNERS, 6th Earl of Rutland, as 17th Baron de Ros (1578-1632).
