a. His parentage is unknown, but he probably derived his surname from Ros in Holderness, Yorkshire. He was steward (dapifer) of the Count of Aumale, lord of Holderness. Piers gave land in Gilling near Helmsley, and the church, to St. Mary's Abbey in Yorkshire.

b. Adeline was the youngest of three sisters and coheirs of Walter Espec, Lord of Helmsley, who was founder of three monasteries, Kirkham (1122) and Rievaulx (1131), both in Yorkshire, as well as Wardon in Bedfordshire (1134). Walter Espec died in 1155 leaving no heirs, and Helmsley, which had been granted to him by Henry I, went to his sister, Adeline, and thus to the Ros family, while Walter's Bedfordshire lands were divided amongst his other two sisters, Albreda, and Hawise. Their father, William Espec, appears in Domesday as a tenant-in-chief of Old Wardon in Bedfordshire.

c. Confirmed to Rievaulx the gift of his uncle Walter Espec in 1147-53, for the souls of his father and his brother, Everard. He was sometimes constable, probably to the Count of Aumale, lord of Holderness. He attested a charter of Count William about 1150, as well as Henry II's charter to Scarborough, where for several years, he was in charge of works at the King's castle.

d. After the death of her first husband, Sibyl married, about 1166, William de Percy (who died bef 1175), and thirdly, in 1181 or 1182, Ralph d'Aubigny (who died 1192).

e. Everard de Ros was still a minor at his father's death. He was a supporter of the King in the rebellion of 1173.

f. 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.

g. William de Ros was included with his father in the Bull of excommunication of January 1215/16, and remained an active ally of Prince Louis until the final battle at Lincoln, 19 May 1217, where he was captured, later paying for his release from prison in October. In the service of the King in May 1224, he was sent to Poitou, and in August of that year took part in the siege of Bedford Castle. In January of 1235/36, he attested the confirmation of Magna Carta at Winchester, and in 1237 he was of the escort of the King of Scots to his meeting with Henry at York, attesting to the agreement between the two Kings. His lands were seized in 1242-43 for failure to attend the 1241 muster at Rhuddlan, and the King's expedition to France in May 1242. In 1252, he went on pilgrimage to Santiago. He and son, Robert, were summoned for service in Scotland 1257/58, against the Welsh in 1258 and 1263/64, and to London in 1260-61. It is stated that he appears to have taken no part in the Baron's war and was reputed to be loyal.

h. Chief commissioner in Herefordshire in 1258 (to inquire as to excesses in that county), summoned the same year, and later, for service in Scotland, and against the Welsh. Sided with Simon de Montfort in 1263/64, and was holding Northampton, under the younger Simon, when the King took it in April, but within several days he had safe conduct to meet with the King. On 24 December he was summoned to de Montfort's Parliament in London. On 18 May 1265, Prince Edward escaped from his custody at Hereford and Robert surrendered Gloucester Castle to the Prince 29 June. Ten days after the battle of Evesham, at the Prince's insistance, Robert received full pardon. In November of 1276, he was one of the Council at Westminster who gave judgment against Prince Llewelyn, and was summoned for the consequent campaign. He was buried at Kirkham, Lancashire.

i. Summoned against the Scots in 1291, and later years, to May 1316, and in 1291, for a short time, was among the candidates for the throne of Scotland. Summoned to Parliament 6 February 1298/99 to 16 October 1315, by writs considered to have become Lord Ros of Helmsley. After the rebellion of Robert de Ros of Wark, who held Wark of him, that castle was granted to him December 1301, for good service in Gascony and elsewhere. Appointed Joint Warden of Northumberland in November 1307, and Joint Lieutenant and Warden of Scotland 21 June 1308. He was summoned to the King's coronation February 1307/08. In addition to his heir, William, he left a younger son, John de Ros (of Watton), and a daughter, Agnes, wife of Payn de Tiptoft.

j. Maud de Vaux was younger daughter and coheir, in 1287, of John de Vaux, son of Sir Oliver de Vaux. She probably predeceased her husband and was buried at Pentney Priory in Norfolk.

k. Residing in Wark Castle in August 1310. He was summoned for service in Scotland 1316-19, 1322, 1323, 1327, and 1335, and to Parliament 20 November 1317 to 21 Feb 1339/40. Received the surrender of Knaresborough, as a joint commander in January 1317/18, and remained loyal during the Earl of Lancaster's rebellion in 1321-22. Summoned for service in Gascony in December of 1324. He was appointed, by Prince Edward's government, Sheriff of Yorkshire (Nov 1326) and was a member of the Council of Regency in February 1326/27. In November 1327, he served as a commissioner to negotiate with the Scots for peace, as well as a similar role with France in February 1329/30. In 1334, he entertained the King at Helmsley, and during the King's absence in Flanders, he was one of the commissioners to preserve the peace in that country. He took part in the defense of Newcastle against the Scots. Buried at Kirkham in Lancashire.

l. Margery was the eldest of four daughters of Bartholomew, first Lord Badlesmere, stated to be aged 32 when she became heir to her brother, Giles. who died 3 February 1342/43. As the widow of William de Ros, she had a royal license to marry whom she would of the King's allegiance, which license, dated 6 Mar 1350/51 was to Sir Thomas de Arundel, who was killed shortly thereafter. She married thirdly (as probably his third wife), Sir John Avenal, the King's Lieutenant in Brittany, from whom she sued for divorce in April 1355.

m. Took part in the King's expedition in Normandy, 1355 and in the campaigns of 1356 and 1359-60. Summoned to Parliament 1362 to 1383, and served as Joint Warden of the West March of Scotland, 1367, and the East March in 1371. In 1368 he was ordered to reside on his lands in Ireland with his armed forces, to prevent loss and destruction of the country, where he served as Trier of Petitions 1363-1377. He was a banneret at the time he was knighted in or before 1372. He died at Uffington in Lincolnshire.

n. Beatrice de Stafford was the widow of Maurice Fitz Maurice, Earl of Desmond, at her marriage to Thomas de Ros. She married thirdly, by 20 August 1385, Sir Richard de Burley, who predeceased her.

o. Privy Council to Richard II and Henry IV, he was summoned to Parliament 1393-1413. He was present at the interview with Henry in the Tower, 29 September, at which Richard signed his abdication, and in the first Parliament of Henry IV on 23 October, assented to the imprisonment of the late King. He served as Treasurer of England, from September 1403 to November 1404. He died at Belvoir and was buried in the priory. His inquisition post mortem mentions younger sons, William, Thomas, Robert, and Richard, and a daughter, Elizabeth, who married Robert, Lord Morley. The Rivevaulx Chartulary records also daughters Margaret, who married James, son of John (Audley), Lord Audley, Beatrice, and Alice. Note that Margaret married James Tuchet, son of Lord Audley, John Tuchet, who took the name Audley, but were, in fact, Tuchets.

p. Presumably the third son of William de Ros (d abt 1264), he was summoned, along with his elder brothers, Robert and Piers, against the Scots January 1257/58. In October 1268 he was summoned to answer for marrying without the King's license, and on 8 June 1294, along with sixty others, including his kin, William de Ros of Helmsley and Robert de Ros of Wark, was summoned to attend the King on urgent affairs in Gascony, and appears to have served there. In addition to his son and heir, William, he left a younger son, Thomas, as well as daughters Mary (a prioress), Margaret, Lucy, wife of Sir Robert de Plumpton, Isabel, wife of Marmaduke de Thweng, and Juetta, wife of Sir Geoffrey Scrope. Sir William de Ros of Igmanthorpe and his wife Eustache, who predeceased him, were both buried in the church of Grey Friars, Yorkshire.

q. Referred to as Robert de Ros of Wark, records show that in April of 1230, he was going overseas in the King's expedition into France, and in 1234, he was appointed a Justice of the Bench in Lincolnshire, Yorkshire, and Northumberland. He was with the King at York, 25 September 1237, when Alexander II of Scotland disclaimed Northumberland, Cumberland, and Westmorland, and was summoned against the Scots in May of 1244. He and John de Baliol were sent as guardians of Princess Margaret, accompanying she and her husband, King Alexander III back to Scotland after their marriage on 26 Dec 1251. In 1255, after Margaret made complain against Robert, he was summoned to England and his lands were seized and large fine levied against him. He was later pardoned as wholly innocent of the charges brought against him, his lands were restored and the fine remitted. He married, perhaps secondly, Christine, daughter and in her issue coheir of Roger Bertram.

r. While the younger son, his father made him his heir, and thus he succeeded to Wark. His wife, Margaret de Brus, was the third of four sisters and coheirs of Piers de Brus, her share of the inheritance being Kendal in Westmorland. Their elder son, and heir, Robert de Ros, who became Lord Ros of Wark in 1295, took the side of the Scots against the Crown of England, and died in poverty shortly before 20 April 1274, his lands forfeited, and his title stripped.

s. Margaret (de Brus) de Ros, who died shortly before 30 Jauary 1306/07, divided her lands between her younger son, William, who founded a family of Ros in Kendal, and her nephew, Marmaduke, 1st Lord Thweng.
