[quote=@Wernher]Technically, since it's 2700 BC, it's actually 4726 years ago. I don't know how recognizable the Seneca and others would be at this point in time.[/quote]
I considered that. I have done some research. They did not form the Iroquois Confederation until the 12th century. The people were there. They called themselves the Onöndowa'ga which means "The Great Hill People". The name "Seneca" is given to the Onöndowa'ga by Dutch explorers based on a pronunciation Mohegans referred to the Iroquoian people originally used for the Oneida. Early Dutch explorers used the word Sennedaas for the four western nations; Oneida, Onondaga, Cayuga, and Seneca. As more and more Europeans made contact with them, the Onöndowa'ga ended up with the anglicized term, "Seneca". The French referred to them as Sonontouans.

Thus far, in my writing, I have not used that term, simply their location in Western New York or what they refer to as the Long Lakes (Finger Lakes). Since there is not a lot written about this area of the world before the 16th century, I feel free to take at least some literary creativity. Although Philip Beaulieu is aware of the Seneca from his own past in the 20th and 21st centuries, he has not used the term. Maybe he fears they will not understand it? Since it is based on a European word.
