Thomas Stone (1743 – October 5, 1787) was an American Founding Father, planter, politician, and lawyer who signed the United States Declaration of Independence as a delegate for Maryland.

[2] Stone was born into a prominent family at Poynton Manor in Charles County, Maryland.

On May 15, 1776, he voted in favor of drafting a declaration of independence, in spite of restrictions from the Maryland convention that prevented their delegates from supporting it.

[4][5] That same year Stone was assigned to the committee that drafted the Articles of Confederation, and he was struck with a personal tragedy.

[4][5] After Stone signed the Declaration of Independence, he took his wife home and declined future appointment to the Congress, except for part of 1784, when the meetings were at Annapolis.

Soon after, Stone purchased his first 400 acres (1.6 km2) and began the construction of his estate named Habre de Venture.

Stone's law practice kept him away from home, so he brought in his younger brother Michael to manage development of the plantation,[4][5] which utilized slaves for generations.
