Jefferson was born at a settlement called Osbornes (Osbornes was also the birthplace of his father, Captain Thomas Jefferson in 1677.) The settlement was a local shipping center and tobacco inspection station. His father, Thomas Jefferson, was a captain in the local militia and justice of the peace. a large property owner, and Mary Field (1680–1715), who was the daughter of Major Peter Field of New Kent County, Virginia, and granddaughter of Henry Soane (1622–1661), a member of the Virginia House of Burgesses.
