Roger de Newburgh, 2nd Earl of Warwick. This nobleman, in the contest between the Empress Maud and King Stephen, espoused the cause of the former, but his lordship is much more known by his munificent grants to the church than his martial deeds. He married Gundred, daughter of William, Earl of Warren, and had issue, William and Waleran, successive earls, Henry, and Agnes. The earl died 12 June, 1153, and was succeeded by his eldest son, William de Newburgh, 3rd Earl of Warwick.
