Ambrose Barlow was a 16th-century English Benedictine monk and priest who served the Catholic community in Lancashire. Born at Barlow Hall in 1585, he was raised in a family that faced significant hardship for their religious convictions. After converting to Catholicism and studying in France and Spain, he returned to England to minister to local Catholics. He is recognized as one of the Forty Martyrs of England and Wales, having been executed in 1641 for his refusal to abandon his faith despite royal decrees against Catholic priests.
