Blackwell, George an English divine of the Roman Church, was born in Middlesex in 1545, and educated at Trinity College, Oxford, and at the English College in Douay. He approved of the oath of allegiance to the crown of England, and advised the Romanists to take it. This led to a controversy with cardinal Bellarmine. He died in Rome, Jan. 13, 1612. His Letters to the Romish Priests, touching the lawfulness of taking the oath of allegiance, were published in 1597. He also published a Letter to Cardinal Cajutane (1596), and some other papers on the same subject. See Allibone, Dict. of Brit. and Amer. Authors, s.v.; Chalmers, Biog. Dict. s.v.; Hoefer, Nouv.
