My namesake, St. Edmund Campion, was a Jesuit priest who was hung, drawn, and quartered under Queen Elizabeth under a charge of "high treason". His "treason" consisted in saying Mass and hearing confessions.
Evelyn Waugh wrote a very fine biography of St. Edmund; it's available through Sophia Press.
BTW, do any of your sources mention that Tyndale was "fingered" to the ecclesiastical courts in Belgium by an agent of the (Protestant) King Henry VIII?
