[2] He was made vice-chamberlain of the household of King Richard II in 1393 and granted the castle and manor of Marlborough in Wiltshire.

[6] He benefitted from the confiscated estates of Thomas de Beauchamp, 12th Earl of Warwick, who was kept for a time under his care in the Isle of Man, and of John of Gaunt; he also accumulated control of a number of strategic castles.

After Hereford's ascendance to the throne as Henry IV, Parliament confirmed the sentence and determined that all his estates and title were to be forfeit to the crown.

In 1869, the Committee for Privileges of the House of Lords, after a series of hearings beginning in 1862 under the title of Wiltes Claim of Peerage 4 HL 126, rejected the claim of Simon Thomas Scrope, of Danby, to the Earldom of Wiltes (Wiltshire) granted to William le Scrope, above.

It was proved that Simon Thomas Scrope was the senior heir male of the Earl of Wiltes, but the Committee for Privileges decided that as a matter of law an English peerage could not descend to heirs male general who were not directly descended from the original grantee; they also rejected arguments based on the irregularity of the original sentence by Henry IV before he had become King.
