This map is a treasure. It dates from the early 1900's and shows the entirety of the estate at it's peak under the ownership of Guillaume Resuens. It shows all the known structures, details on when various parcels of land were acquired, the extensive water/piping system that ran throughout the property, and much much more. Big thanks to the McAndrews family for donating this to our group, and the Westchester County Archives for scanning it. Please be patient while this rather large image loads. Enjoy!
