The settlement of Lord Baltimore's Maryland began with the arrival of passengers from England at St. Clement's Island in the Potomac River in what is now southwestern St. Mary's County on March 25, 1634.  The passengers arrived in two vessels, the Ark and the Dove, which had set sail from the Isle of Wight on November 22, 1633. St. Mary's County was the first county established in Maryland, in 1637, probably by an order of the Governor.  The county seat and state capital was St. Mary's City.  The county seat was moved to Leonardtown. The county was also home to the first Catholic Mass celebrated in the original thirteen colonies.
