Penkridge now became enmeshed in the meteoric career of John Dudley, Earl of Warwick, a key figure in Edward VI's regency council. In 1539, Dudley got control of Penkridge manor by foreclosing on a debt its owners, the Willoughby de Broke family, had owed to his father, Edmund Dudley. Next he grabbed the Deanery Manor and Tedesley Hay, making him the most important landowner in the area, although day-to-day management of the deanery lands stayed with the Littletons, the lessees. Dudley went on to seize almost absolute power in England, and taking the title Duke of Northumberland. Edward's early death in 1553 left Dudley high and dry. Edward's older sister, the Catholic Mary, succeeded but Dudley attempted a coup d'état in favour of Lady Jane Grey. Mary prevailed and Dudley was arrested and beheaded as a traitor. His lands were forfeit to the Crown, the extensive estates at Penkridge among them.
