Priest and martyr, born probably at Terling, Essex, England, about 1498; died at York, 11 May 1537. He was the third son of John Rochester, of Terling, and Grisold, daughter of Walter Writtle, of Bobbingworth. He joined the Carthusians, was a choir monk of the Charterhouse in London, and strenuously opposed the new doctrine of the royal supremacy. He was arrested and sent a prisoner to the Carthusian convent at Hull. From there he was removed to York, where he was hung in chains. With him there suffered one James Walworth (Wannert; Walwerke), Carthusian priest and martyr, concerning whom little or nothing is known. He may have been the “Jacobus Walwerke” who signed the Oath of Succession of 1534. John Rochester was beatified in 1888 by Leo XIII.
