It is divided into two sections, treaties held with Senecas residing in what is now New York and Ohio. Current and future generations of Senecas and Americans should be aware of these treaties and their significance. The 1794 treaty remains in effect today in perpetuity. Genealogists will appreciate the plethora of Seneca signatures on these documents. Every library should have a copy of this book.
