Overview
William Devereux was an Anglo-Norman nobleman living during the reigns of kings William I, William II, and Henry I of England. The Devereux, along with the Baskervilles and Pichards, were prominent knightly families along the Welsh marches at the beginning of the twelfth century, and linked to the Braose and Lacy lordships of the region. William Devereux's descendants would later give rise to the Devereux family of Hereford, and the Devereux Viscounts of Hereford and Earls of Essex.
Career
Following the Norman conquest of England, William Devereux was granted lands along the Welsh Marches in Herefordshire, Shropshire, and Gloucester as a member of the retinue of Walter de Lacy. Shortly after the Battle of Hastings rebellion broke out along the Welsh marches. Devereux probably participated in efforts to counter the attacks of Eadric the Wild and the Welsh on Hereford. In 1069, Walter de Lacy countered an attack and then led a retaliatory raid into Wales. Eadric the Wild burned Shrewsbury, but unsuccessfully besieged its castle. Late in 1069 King William led the local forces in defeating Eadric the Wild at the Battle of Stafford, and forcing his submission in 1070.
In 1075 the Revolt of the Earls broke out against King William’s rule. It was led by Roger de Breteuil, earl of Hereford; Ralph, earl of East Anglia; and Waltheof, Earl of Northumbria. Walter de Lacy, and probably William Devereux as part of his retinue, played a critical role in preventing the earl of Hereford’s forces linking up with the other rebels, which lead to the collapse of the revolt.
William Devereux probably would have attended the king as he spent Christmas of 1080 at Gloucester. Devereux would have been expected to participate in king William’s movement into Wales in 1081, which may have been a military raid to quell local resistance.
