John Roche (martyr)
He helped Saint Margaret Ward arrange the escape of Father Richard Watson from Bridewell Prison when the boatman she had originally asked to help her refused to do so. Roche exchanged clothes with the prisoner and was arrested in his place. Offered his freedom if he would ask Queen Elizabeth I's pardon and promise to attend a Protestant church, he refused, and was hanged at Tyburn, London on 30 August 1588, along with Ward, Edward Shelley, Richard Martin, and Richard Leigh and Richard Lloyd (alias Flower).
In addition to this, a school in the London borough of Tower Hamlets was named after him.
