The Pro Maria Committee was founded in 1949 in Lowell, Massachusetts by Joseph Debergh, O.M.I. The purpose of the Committee was to disseminate the story of Our Lady's thirty-three appearances in Beauraing, Belgium in 1932 and 1933. The Committee promotes an Association of Prayers called the Marian Union of Beauraing, distributes pamphlets, leaflets, medals, and published a book; Our Lady of Beauraing (1958).
