Who they were

Arthur of Glastonbury (c. 1539), according to some French sources, was an English Catholic in the sixteenth century. He was martyred during the period of King Henry VIII's suppression of the Catholic Church due to his refusal to accept the king's claim to spiritual leadership of the Church in England.
