I am also researching for similar purposes. The info you ask for is best gotten at a library, and at sites which would give you more info than this site is designed to give. The Texas U. website that Dee posted is an excellent one, and the book JC recommended is an excellent one, if you check those posts. It sounds like a very interesting project. The DR would make an excellent setting for such a play. You might start with Columbus, himself, as he supposedly introduced Christianity to the DR, though the example he gave and the Church people in general was a misrepresentation of Christianity. You might also study Bartolome de las Casas, who became a priest and tried to defend the Indians, and Fr. Montesino, one of the early Dominicans. Santo Domingo is the name of the patron of the Dominican Order and of the country. The Catholic Church remains strong there, though changed much since Columbus' time - thank God. There also are groups that practice voodoo, santeria, brujeria, and Satanism.
