The Thomas Stone House is located on Rose Hill Road in Port Tobacco, Maryland. It is part of the Thomas Stone National Historic Site. Stone was born in Charles County, Maryland in 1743 and would go on to become a lawyer, a delegate to the Continental Congress in 1775 and in 1776 one of the fifty-six signers of the Declaration of Independence. Stone was also a member of the Maryland Senate from 1779 to 1985. He began construction on what would be known as Haberdeventure in 1771. Initially the house was to be a small residence for him and his immediate family, but it soon grew in size to a large plantation. Stone died in Alexandria, Virginia in 1787 and was buried on the grounds of his estate in the family cemetery, next to his wife Margaret, who had predeceased him by only a few months. The house and lands remained in the family until 1936. In 1977 a fire seriously damaged the house and shortly thereafter the National Park Service purchsed the property and began restoration on the home. The house was declared a National Historic Landmark in 1971.
