Looking for more info on the Duplin ROBERTSON family that shows up in the 1880 Ballard Co., KY census.

Particulrarly, who were his parents. I''m trying to find the connection between him and the Stanford ROBERTSON family that lived in Carroll Co. TN for 29 years till 1863 when they moved to Montgomery Co., IL.

James PEACOCK, a relative of one of my ancestors, was living with the Duplin ROBERTSON family in 1880. His mother was Alpesine Eve (ROBERTSON) PEACOCK, daughter of Stanford ROBERTSON from Carrol, TN.

Here's the 1880 census info:
