[alias Spence] English martyr, executed at Durham, 4 February 1593-4, for assisting the venerable martyr Saint John Boste, whom he used to escort from one Catholic house to another. He died with constancy, despising the inducements offered to bring him to conformity. With him was condemned Mrs Grace Claxton, wife of William Claxton, of the Waterhouse, in the parish of Brancepeth, Durham, at whose house Boste was taken and probably Speed also. She was, however, reprieved on being found to be with child.
