There is a map of Saratoga County in David Burr's Atlas of New York State (1829). You can find the atlas at New York State Library and many other large libraries in New York State. You can probably find other maps of the Kayaderosseras Patent at the New York State Library and Archives. In addition, check with the Special Collections Dept. at the Syracuse University Library. They have a number of manuscript maps of the Kayaderosseras Patent in their Geritt Smith collection. David Allen Map Librarian SUNY Stony Brook
