John Wall was a 17th-century English Franciscan priest and martyr born in Preston. After studying at the English College in Douai and later in Rome, he joined the Order of Friars Minor, taking the religious name Joachim of St. Ann. He spent over two decades serving Catholic communities in Worcestershire, often using various aliases to evade government spies. His long ministry ended when he was arrested during the period of the Titus Oates plot, leading to his execution for refusing to renounce his faith.
