Since you ask about Eatons, I don't have the exact ones you are looking for, but I do have a Burton Eaton, born in 1795 in Granville County. His wife's name was Susan and they had at least two children, Betsy and Richard. Betsy "married" William Burwell, had a daughter Gertrude Eaton that married Gilbert Bullock. I also have two Eaton women, Ellen who "married" moses Bullock circa 1844,and Roxanna who married Lewis Burton. I do not have parents for them, but they all resided in granville County, NC.
Now, for the plantations in that area. I am researching Bullocks, Burtons and Brames and the associated families. My ggggrandfather's name was Eaton Burton. MONTPELIER, was the colonial home of Judge John Williams. There is documentation in Granville County Courthouse to support the fact that he "gave" it to Col. Robert Burton along with most of what is now Williamsboro and Townesville. Col. Burton married Judge Williams'only child. Montpelier was know as the Burton Plantation and remained in the Burton family (plats were sold off to establish the town) during the Civil War. Sometime between 1880 and 1900 the land apparently passed on to the Bullock Family. Judge Williams wife was a Bullock.

According to this historical map of Granville County, There was at least one Eaton Plantation just south of Henderson. The name appears to be BearPond. There are other plantations listed by the owners names and the dates they were built. Churches are noted as well. The map was made in 1931 by JE Buck. You can get a copy in their office (Vance) for about a dollar.
