first bishop of the RC hierarchy in the USA. A native of Maryland, he was trained at St-Omer and became a Jesuit in 1753. When the Jesuits were suppressed in 1773, he returned to America. Partly through the influence of Benjamin Franklin, in 1784 Pius VI appointed Carroll Superior of the Missions, a step which made the Church of the USA independent of the Vicars Apostolic in England. In 1789 Carroll was appointed Bp. of Baltimore; in 1808 he was made an archbishop, his diocese being divided into four sees.
