William de Ros, 6th Lord de Ros of Helmsley succeeded to the title of 6th Lord de Ros of Helmsley on 6 August 1393. He was invested as a Privy Counsellor (P.C.). He held the office of Lord Treasurer from 1403 to 1404. He was invested as a Knight, Order of the Garter (K.G.) in 1404.

His first assignment from Richard II of England was to join Walter Skirlaw, Bishop of Durham, Henry Percy, 1st Earl of Northumberland and others in negotiating for a peace treaty with Robert III of Scotland. Richard favored William with a position in his Privy council. In 1396, William accompanied the King to Calais for his marriage to his second Queen consort Isabella of Valois, daughter of Charles VI of France and Isabeau of Bavaria.

When Henry of Bolingbroke started his revolt against Richard II, William was among the first to support him. He was present for the abdication of Richard II and the declaration of Henry IV as the new King. He retained his position in the Privy council for the rest of his life.

He seems to have been a special favourite with the first monarch of the House of Lancaster and was employed by him in various civil affairs of great importance. He served as Lord Treasurer of England from 1403 to 1404. He was created a Knight of the Garter in 1403 along with Edmund de Holand, 4th Earl of Kent and Richard Grey, 4th Baron Grey of Codnor.

William was in charge of investigating the activities of Lollards in Derbyshire, Middlesex and Nottinghamshire from 1413 to his death.

• William De ROS (7º B. Ros of Hamlake)
• Born: ABT 1369, Hamlake, Yorkshire, England
• Died: 1 Sep 1414, Stoke Albany, Northamptonshire, England
• Buried: Belvoir
• Notes: Knight of the Garter. Lord Treasurer of England. Brother & Heir to John de Ros, aged 24 at his brother's death. Summoned to Parliament from 20 Nov 1394. According to Cockayne's "Complete Peerage", he was summoned to parliament regularly 1394-1413. He served on the Privy Councils of both Richard II and Henry IV. He was in Calais in 1396 for the wedding of Richard II to Isabelle, the 8 year old daughter of King Charles VI of France. This marriage was very unpopular with the English nobility and added to their discontent with the King's rule in general. In 1399, while Richard was on an expedition to Ireland, Henry Bolingbroke, the Duke of Lancaster (the future Henry IV), who had been banished by Richard, returned to England with an army to claim the throne for himself. William threw his support to Henry. He was present at the abdication of Richard and assented to his inprisonment (which led to his death shortly thereafter). William was Treasurer of England in 1403 &1404; made a Knight of the Garter in 1404; was one of the auditors of he war accounts in 1406; and in 1413-14 was the King's chief commissioner for the shires of Middlesex, Nottingham, and Derby in the matter of determining the facts relating to rebellions and treasons commited by the Lollards.
