Old copies of the Cheshire County plat book turn up at auctions and in kitchen drawers around Dublin, and new ones are harder to track down. Here's what a plat book is, where to look for one in Cheshire County, and the free official map that stays current between editions.
What's inside a county plat book
Private publishers compile plat books from county records, so a county edition is a snapshot of who owned land near Fitzwilliam the year it was printed. Deeds and recorded plats, not the atlas, still govern land near Troy in the county.
Step one: the free Cheshire County viewer
For Cheshire County, the free public parcel layer is state-run: open the NHDOT Parcel Mosaic Viewer and pan to Gilsum. Expect a disclaimer screen the first time you open the Cheshire County map; accept it and the parcels load. Use the search box for an address in Keene or a parcel number, or simply zoom in and click a tract close to Gilsum. If the official address for the Cheshire County, NH map ever changes, our directory page carries the current link for Keene and the rest of the county.
Finding a printed Cheshire County plat book
Try the library in Fitzwilliam or a local historical society for older Cheshire County editions; libraries sometimes keep past atlases for reference. An old atlas can help trace when a tract close to Harrisville split off from a larger farm.
Cheshire County land records
For land near Chesterfield, the deed itself lives in the county recording office, and the map is an index to it. Easements and access rights near Fitzwilliam live in recorded documents, so read the deed, not just the county map.
Current owners without a printed book
For current ownership, the free NHDOT Parcel Mosaic Viewer beats any printed book: owners update as deeds are processed, and you can click any tract close to Fitzwilliam. Phone signal can be thin near Troy, so save the parcel IDs you need before you head out.
Atlas details and limits
Plat book pages for Cheshire County usually include an index of owners, so you can locate a family name near Dublin without knowing the township. Owner names in an older Cheshire County edition may be decades out of date, so confirm on the county map before contacting anyone near Troy. For a land purchase near Dublin, rely on the county parcel record and a title search, not an atlas.
Editions, deeds and printouts
Comparing two Cheshire County editions side by side shows when a farm near Chesterfield was split or sold. Saving PDFs of the county map around Troy gives you an offline reference when the signal drops.
