Theodorick Bland (February 1663 – November 1700) made a  survey in 1693 of the Howson Patent, which is an area corresponding to present day Alexandria, Virginia. He also made a survey for  Williamsburg, Virginia in 1699.   
Bland was the oldest son of
Theodorick Bland of Westover and Anna Bennett, the daughter of Governor Richard Bennett.  His brothers were  Richard Bland (who had many notable descendants) and John Bland (who was the great-grandfather of Chancellor Theodorick Bland).  Bland married Margaret Man and had two sons:  
John Bland (born December 8, 1698); he married Ann West and had at least three children, John, Theodorick, and Mary.
 Theodorick Bland, who died shortly after his father.
When his father died in 1671, Bland inherited
Westover Plantation and joined with his brother, Richard, in its ownership. The brothers eventually  conveyed 1,200 acres of the property to William Byrd I in 1688 for 300L and 10,000 pounds of tobacco and cask. Byrd's grandson built a Georgian mansion there in the 1750s.
