MINOR LINE
!Treasurer of William Rufus. Following William II's death in the New Forest, he raced for the Treasury at Winchester and arrived at the same hour as Prince Henry (later Henry I). Henry demanded the keys. William de Breteuil insisted that they should not be given up, saying that Prince Henry, as well as himself,
had paid Robert, the elder brother, homage, and that he was the rightful successor. Henry drew his sword, and at length, by force and persuasion, obtained the royal treasures. The next step was easy. He was crowned at Westminster on Sunday, Aug. 5, 1100. [Knight's Popular History of England, Vol. 1, p. 261]
