I don't know if anyone has checked out the map-history of Greenfield at www.old-maps.com BUT now there is a new booklet out delineating the historical boundaries of Hinsdale, NH at the same web site. This would be of interest to Franklin county researchers because the town was part of Northfield before the state line chopped it off. Reproductions of historical maps show many property owners and businesses. This would be a worthwhile project to index--much easier to read than the Greenfield maps, because of the size of the town.
