This page is dedicated to those researching ancestors from historic St. Mary's County, Maryland. St. Mary's was founded when Governor Leonard Calvert and about 140 passengers on the Ark and the Dove sailed from Isle of Wight, England on November 22, 1633 and erected a wooden cross on nearby St. Clement's Island, Maryland on March 25, 1634. After a century or more of war, persecution, and intolerence over the conflict between Catholicism and Protestantism in England, St. Mary's was founded on the principle of "Freedom of Conscience" and religious tolerance. Thus, a large number of its early settlers were Catholics, seeking the freedom to worship under the religion of their choice. Freedom of religion was made law in 1644 at St. Mary's City, then the capital of Maryland.


~Freedom of Conscience~

Right: "Here, for the first time in America, men and women of differing faiths lived in peace and goodwill, practicing freedom of conscience."

Also included are a replica of the square-rigger The Dove, some fully reconsructed buildings, archealogical digs, museum and presentation center.

Ironically, the freedom of religion in St. Mary's County did not last long. Because of their tolerance for religious beliefs, St. Mary's invited the Puritans to settle there to escape the persecution they had endured. The Puritans then overthrew the lawful government, and began to persecute Catholics and Anglicans alike, controlling Maryland from 1654 to 1657. In 1692, England sent a new governor to take control of Maryland, and made the Church of England the official religion of Maryland. The Catholic Calverts converted to Protestants and they regained control in 1715. Catholics were forbid to participate in government, were no longer allowed to worship together, and in 1704 a law was passed calling on Catholic children to rebel against their parents. Any Protestant widow who married a Catholic lost custody of her children, and special taxes were levied on land owned by anyone practicing the Catholic faith.

Many of Maryland's catholic families, half of whom lived in St. Mary's County, began a migration to Kentucky, then later to Missouri. The west side of the Mississippi River was controlled first by the French, then the Spanish, and both governments welcomed Catholicism. Many St. Mary's families settled in Nelson, Marion, and Washington counties in Kentucky, and later in Perry County, Missouri.
