ST. MARY'S COUNTY, MARYLAND

[County Seal, St. Mary's County, Maryland] Origin: What would become St. Mary's County was land where the Conoy Indians lived. Here, the settlement of Lord Baltimore's Maryland began with the arrival of the passengers who had set sail on the Ark and the Dove from Cowes, England, on November 22, 1633. They landed at St. Clement's Island in the Potomac River on the southwestern side of present-day St. Mary's County on March 25, 1634. The date of their landing is commemorated annually as Maryland Day.

Established in 1637 (probably by an order of the Governor), St. Mary's, the first Maryland county, was named in honor of Mary, the mother of Jesus.
