(1559–98), Franciscan priest and martyr. Born at Clynog Fawr (Caernarvonshire), he joined the Franciscan Order at Pontoise (France) c.1590, presumably as a priest. He was professed in Rome at the Ara Coeli church in 1591 and returned to England to work in and near London the following year. He became closely associated with Henry Garnet, S.J. In 1597 he was arrested and kept in prison for a year, pending the collection of evidence. The charge was that as a priest ordained abroad he had returned to minister in England. He was found guilty on his own admission and was executed on 12 July at St Thomas Waterings on the Old Kent Road, Southwark. During an hour's delay on the scaffold because the executioner had forgotten his rope, Jones asserted that he had never entertained even the thought of treason. He was canonized by Paul VI in 1970 as one of the Forty Martyrs of England and Wales. Feast: 25 October.
