The Embury-Wilson Patent
The Patent with its subdivisions as it existed between 1773 and 1776

Below is much of the Embury/Wilson Patent as overlayed onto Google Earth. This is just eyeballed and is probably off somewhat. I hope to geolocate it this summer. The lower three colored areas are the Cambridge, Gregor, and Bain Patents from left to right. In between them and Embury are the Grant & Campbell and Schermerhorne Patents.
