However, soon after 1086 William II created the earldom of Warwick for Henry de Beaumont, who changed his name to Henry de Newburgh, appointed him Constable of Warwick Castle and gave him the great estate of Thorkell of Arden. It is not known why Thorkell was dispossessed, he may have only been granted a lifetime tenure of his lands the estate passing to the Crown on his death or it may have been that his son died before him and that he left no direct heir. His family, the Ardens however, held land from the Earls of Warwick for another 200 years.

He received the estate of Thorkell of Arden. The reason for Thorkell's disinheritance is unclear; he might have been granted a lifetime tenure that would pass to the Crown upon his death or had no direct heirs due to his son's early demise. Despite this, the Ardens continued to hold land from the Earls of Warwick for another 200 years.
