In colonial New York the westernmost tribe was the Senecas, whose hunting-grounds extended from the Central Lake District to Lakes Ontario and Erie. When the Dutch pioneers encountered these Indians they were found to have the almost unpronounceable name of "Tsonnundawaonos," meaning the "great hill people," and the nearest the Dutch could come to it was to call them "Sinnekaas," which in time was changed to Senecas. The Quakers took great interest in them, with such fostering care that three thousand Senecas now live on the sixty-six thousand acres in their reservations. They have their own Indian language and special alphabet, and portions of the Scriptures are printed in it. In their days of power they had two famous chiefs--Cornplanter, also called Captain O'Beel, the name of his white father, he being a half-breed, and Red Jacket. The latter lived till 1830 in the Senecas' village near Buffalo. His original Indian name was Otetiani, or "Always Ready," and the popular title came from a richly-embroidered scarlet jacket given him by a British officer, which he always had great pride in wearing. He was a leader among the Indians of his time and an impressive orator. Next eastward of the Senecas were the Cayugas, who, when discovered by the French on the banks of their lake, had about three hundred warriors, and in the seventeenth century, under French tutelage, their chiefs became Christians. A remnant of the tribe is in the Indian Territory. The Onondagas were the "men of the mountain," getting their name from the highlands where they lived, south of Onondaga Lake. There are about three hundred now on their reservation and as many more in Canada. Their language is regarded as the purest of the Iroquois dialects, and its dictionary has been published. Farther eastward, where the granite outcroppings of the southern Adirondack ranges appeared, were the Oneidas, the "tribe of the granite rock," now having on their reservation at Oneida Castle over two hundred, with many more in Wisconsin and Canada. The Tuscaroras came into the league in 1713, and were given a location on the southeastern shore of Oneida Lake, and they are now on a reservation in Western New York, where over three hundred live, with more in Canada. Their name was of modern adoption, after they had assumed some of the habits of the whites, and means the "shirt-wearers."
