I have recently purchased this book (at $50+) from the Flagship Niagra League in Erie PA. It has 908 pages with an index of names and full coverage of the Sullivan Expedition on 1779 as well the earlier history of the American Revolution. To my great joy, I found numerous references to my ancestor, SIMON SPALDING. I'd be willing to do lookups if you can be patient. Jean Spalding Barbour
