Ampthill Plantation was located in the Virginia Colony in Chesterfield County on the south bank of the James River about four miles south of the head of navigation at modern-day Richmond, Virginia. Built by Henry Cary, Jr. about 1730, it was just upstream of Falling Creek. It was later owned by Colonel Archibald Cary, who maintained a flour mill complex and iron forge at the nearby town of Warwick. Mary Randolph was born there in 1762.
