Greenfield was the home of William Preston though I'm not sure how much the boundaries of the original Preston land overlaps with the current Greenfield Education Center/Industrial Park. The Prestons were a prominent family in Botetourt/Montgomery and there is quite alot on the web about them. My ggggrandparents, Thomas and Nancy Sesler, owned land adjoining Greenfield and the Great Road as did Edward McDonald and the Gish family (after 1790 and until at least 1823). Phyllis Yoshida
