Bedford County was formed in 1754 from the northwest part of Lunenburg and a small part of Albemarle. In 1755 the Act creating Bedford County specifies that "Lunenburg be divided, from the mouth of Falling River up the said river to the fork, thence up the fork running by John Beard's to the head...and all that part of said Lunenburg shall be called by the name of Bedford..." [The Old Free State pg 142]. The border between Lunenburg and Albemarle was the divide between the James and Roanoke River watersheds. After Bedford was formed, this border was found to be impractical, and a line was drawn in 1756 from Flood's Mountain (one of the "Appomattox River Mountains") to the mouth of Stonewall Creek on the James River and all former Albemarle land southwest of that line and south of the James was added to Bedford.
