People who grew up near Auburn remember the Cayuga County plat book as the book that named every farm. Below is how to track one down for Cayuga County, NY, and what the online map does better.
What a Cayuga County plat book is
Think of the Cayuga County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Conquest. Deeds and recorded plats, not the atlas, still govern land near Sherwood in the county.
Finding the tract on the Cayuga County map
For land around Brutus, open the Cayuga County ArcGIS parcel map (an Esri ArcGIS web map); it's the map Cayuga County itself publishes. Most people track down their Cayuga County tract fastest by searching an address in Brutus, then clicking the outline. For a backup route to the map covering Brutus, our Cayuga County directory entry keeps the link current.
Deeds and plats behind the Cayuga County map
The parcel layer for Cayuga County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). A deed book and page or instrument number on the county record is the quickest route to order the document for a lot in Aurelius.
Current and older editions
Try the library in Auburn or a local historical society for older Cayuga County editions; libraries sometimes keep past atlases for reference. An old atlas can help trace when a tract close to Conquest split off from a larger farm.
Current owners without a printed book
For current ownership, the free Cayuga County ArcGIS parcel map beats any printed book: owners update as deeds are processed, and you can click any tract close to Auburn. Pair the county map with a road atlas for the back roads near Conquest.
What a plat book page lists near Auburn
Plat book pages for Cayuga County generally include an index of owners, so you can track down a family name near Fleming without knowing the township. Small parcels and town lots in Auburn are often too small to label on an atlas page, which is another reason the online map is better for them. If you use a plat book for hunting permission near Auburn, recheck the landowner on the county map first.
Making your own atlas of Cayuga County
Farm families near Brutus often keep successive editions of the Cayuga County plat book, which together display how ownership shifted over decades. Some buyers print the county parcel map at township scale to carry on back roads near Aurelius.
The Cayuga County economy in brief
Cayuga County's 2022 business count was 1,512 establishments, with retail trade, construction, and accommodation and food services the largest groups. Compared with national shares, Cayuga County leans toward beverage and tobacco manufacturing and museums, historical sites and parks, which shapes demand for land near Conquest.
