English martyr, b. at Barton, near Farndon, Cheshire; executed at Chichester, 1 October, 1588. Educated at Cambridge, and ordained at Reims in 1585, he was captured on board ship at Littlehampton, Sussex, 19 April, 1856, with three other priests, Thomas Bramston, George Potter, and his fellow martyr, Edward James (b. at Breaston, Derbyshire, about 1557), educated at Derby Grammar School, St. John’s College, Oxford, and the English colleges at Reims and Rome; ordained by Bishop Goldwell of St. Asaph in October, 1583; all were sent up to London and committed to prison 27 April, 1586.
After the failure of the Armada the Government determined to revenge itself on some of the priests in its custody. Crockett and James with two others, John Oven and Francis Edwardes, were selected for trial, which took place at Chichester on 30 September, 1588. All were condemned to death, under 27 Eliz. c. 2, for being priests and coming into the realm; but Oven on taking the oath of supremacy was respited. The other three were drawn on one hurdle to Broyle Heath, near Chichester, where Edwardes recanted, but the other two suffered with great constancy after absolving each other.
