  (Henry Duke Councilor His Descendants and Connections, page 434)
  
  Isabel de Bolebec, countess of Oxford (1165 – 3 February 1245) was eldest daughter and co-heiress of Hugh II de Bolebec, lord of Whitchurch, Buckinghamshire, England (d. c. 1166) and his wife Margaret de Montfichet. Isabel was a patroness of the Order of Friars Preacher (Dominicans) in England.
  
  She married first Henry of Nonant (Novaunt), lord of Totnes, Devonshire who died childless in 1206. In 1207, she petitioned the Crown for the right to marry whom she wished. She received permission, and that same year she married Robert de Vere, heir to the earldom of Oxford.[1] Her only known child, Hugh de Vere (later fourth earl of Oxford), was born within the next year, and Isabel became countess of Oxford when Robert inherited the earldom from his brother in 1214.
  
  Earl Robert joined the barons whose dissatisfaction with King John of England prompted their rebellion, and the earl was one of twenty-five barons elected by the terms of Magna Carta to ensure the king's continued good behavior. That position led to his excommunication when Pope Innocent III released John from the terms of Magna Carta, and the king took Castle Hedingham, Essex, the earl's seat, in 1216.
  
  Robert made peace with the regents of John's son, Henry III of England, in 1217 and eventually served as a judge until his death in 1222. The widowed Countess Isabel purchased the wardship of her minor son and his inheritance for 6000 marks. They travelled together on pilgrimage "beyond the sea" in 1237.
  
  Countess Isabel was one of the chief benefactors of the Dominican Order in England. She assisted the friars sent to England in 1221 to find quarters in the city of Oxford, contributing to the building of their oratory there c. 1227. When the friars needed a larger priory, she and the bishop of Carlisle bought land south of Oxford and contributed most of the funds and materials needed. She was buried in the new church there.
  
  The countess was litigious, engaging in a number of lawsuits, including one long dispute with Woburn Abbey.
