Throughout the years, numerous organizations offered aid to immigrants at Ellis Island. . . . Known under several titles (missionary, chaplain, agent, matron, port worker, colporteur, or social worker), the dedicated men and women of these organizations provided many things, including counseling, guidance, information, translation, money, food, clothing, books, periodicals, gifts, and religious instruction and services.
