Question: Who built the Dockery Plantation, a 25600 acre cotton plantation and sawmill in Dockery, Mississippi?
Context: Brierfield Plantation was a cotton plantation located in Davis Bend, Mississippi, south of Vicksburg and the home of Confederate president Jefferson Davis.

Davis (1784-1870), and had previously been a part of Joseph Davis's much larger Hurricane plantation which it adjoined on a bend of the Mississippi River twenty miles from Vicksburg.  With financial assistance and slaves given by his brother, Jefferson Davis became a successful planter on the acreage following his brief first marriage to Sarah Knox Taylor (who died of malaria a few months after their wedding); after his second marriage to Varina Banks Howell in 1845, Davis erected a large comfortable frame house on the property that was home to himself, his wife, their children, as well as Davis's widowed sister and other relatives.
