[14] Ralph Cromwell, fourth Baron Cromwell, who was Lord Treasurer for Henry VI., and was the builder of Tattershall Castle, died childless in 1455. His sister Maud married Sir Richard Stanhope and had a daughter Maud, whose husband Sir Humphrey Bourchier, third son of Henry Bourchier Earl of Essex, by the Princess Isabel Plantagenet (aunt of Edward IV.), took the title of Lord Cromwell _jure uxoris_. This Lord Cromwell seems to have been a student of law as well as a soldier. There is a manuscript copy of the statutes of Edward III. in the Hunterian Library of Glasgow University which once belonged to him. At the beginning there is the following entry: '_Eximii et preclari militis liber, Johannis Markham capitalis just, de B. Regis, Liber Humfredi Bourchier dmus Cromwell ex dono supradicti_'; and at the end: '_This boke is mine Humphrey Bourchier Lord Cromwell by the gift of the right noble and famous judge Sir John Markham Chief Justice of the King's Bench_.' [15] Sir John Bourchier, fourth son of William Bourchier Earl of Eu, by Anne, daughter of Thomas Duke of Gloucester, married the heiress of Sir Richard Berners, and was summoned to Parliament as Lord Berners in 1455 to 1472. The second Humphrey Bourchier who was slain at Barnet was his son. Fabyan and Habington call him 'Lord Barnes.' [16] Fabyan gives the number at 1,500. Habington says 4,600. Hall is unreliable as usual. He says 10,000 on both sides. Although some writers say that the King's army was superior in numbers, it is probable that, while Edward only had 9,000 men, the forces of Warwick were very much more numerous. {53} CHAPTER V MARGARET OF ANJOU AND HER SON EDWARD It is necessary to look back a few years in order to consider the lives of the mother and son who now, for a time, come prominently into connection with the life story of Richard Duke of Gloucester.
