In 1913 the Marian Fathers first settled in Chicago, Ill., and from there spread to Wisconsin, Michigan, New York, Connecticut, Massachusetts, and Washington, D.C. Some of them minister in the Byzantine-Slavonic rite. In the spirit of their founder, they preach missions, teach, administer parishes, and publish newspapers, books, and periodicals.
