Rocky Boy Tribe of Chippewa Indians of Montana
They were absorbed by the Chippewa Lenni Lenape of Delaware Tribe. They originally lived in what is now called New England. They are actually Chippewa Indians who originally lived in the Alberta, Montana, and Wyoming region before the whites invaded. According to Chippewa authors from the 19th century, the Chippewa's forced their way east from the west. Those Chippewa's are the Lenni Lenape or Delaware Indians. A book written before 1832 and released in 1832 titled "The Edinburgh Encyclopedia," clearly states that the Lenni Lenape along with the Assiniboine (the author classified them as Iroquois but today they are classified as Nakoda), forced their way to the east from a location to the west near the Missouri River. The author wrote that the Iroquois (Assiniboine) joined in the eastward migration with the Chippewa's but kept to the north. They (the Assiniboine) are also known as the Seneca. Seneca is a Chippewa word which means "it has stones,". The correct Chippewa pronunciation for Seneca is "As-sin-i-ca." They (the Assiniboine and Assinica) are really Chippewa's who absorbed many non Algonquin's. Click here to read the Edinburgh Encyclopedia.
And the author of the 1832 Edinburgh Encyclopedia, also knew that after reaching east of the Great Lakes, a large force of the Lenni Lenape were instructed to force their way northwest to the southern shores of Hudson Bay. This probably happened sometime in the 17th century after the whites commenced to sail into Hudson Bay on a frequent basis. From Hudson Bay, the Chippewa's or Chipewyan, forced their way to the northwest and invaded what is now northern Manitoba, northern Saskatchewan, Nunavut, and the Northwest Territories. They also forced their way into Alberta, British Columbia, Yukon, and Alaska. They drove back Asian invaders who were brought to Alaska and the extreme northern part of Yukon, Northwest Territories, and Nunavut by the whites. They are the Aleut and Eskimo. They are not the Gwich'in.
This Chippewa forced migration to the east, commenced in the early 16th century, after they learned that the long awaited white invasion had commenced. Any tribes who protested were eliminated or forced to get out of the way. Chippewa leaders were motivated by the Seven Fires Prophecy. The author of the Edinburgh Encyclopedia wrote that the whites thought the Algonquians had recently invaded North America from Asia. He wrote of a possible language relationship between the Mongol Tarters and the Algonquians. It's the other way around. The Chippewa's invaded Asia and are the Mongols or Tartars. Read the Seven FIres Prophecy. They now have a Language Family known as the Dene-Yeniseian. Of course, the Dene are the Athabascan People who include the Apache, Chipewyan, Navajo and others. The Yeniseian live in central Siberia and are probably related linguistically with the Barushaski of northern Pakistan and Jammu and Kashmir in India.
After reaching the New York and Quubec region in the 16th century, these Chippewa's subjugated the native Algonquians and non Algonquian Tribes. Many of the non Algonquian Tribes formed alliances with the white invaders which enraged the Chippewa's even more. From Quebec and New York, they forced their way south into Virgiania and North Carolina. They are known as the Lumbee and Powhatan in those locations. They absorbed the native Indians and forced them to migrate west after the whites defeated the Chippewa's during the so called Revolutionary War. Many of the Chippewa's migrated even further south into Florida then invaded the islands in the Caribbean and northern South America.
By the early 19th century, the Delaware or Lenni Lenape including the Mahican (included as Mahican are the Stockbridge who were absorbed by the Chippewa's and according to the Ottawa author Andrew Blackbird, spoke a dialect of Chippewa), Munsee, and Nanticoke, were living in the Ohio Valley region. They were under the protection of the Chippewa's but were prone to stay neutral and even side with the white invaders. Before and after the War of 1812, several Reservations were created for the Lenni Lenape in Ohio and elsewhere. The United States refused to honor the treaties which created these Reservations which means these Reservations are still legitimate. Some Lenni Lenape live in Ontario, Canada. Some live in Oklahoma. And out west in Colorado and Idaho, are groups of Delaware trying to gain federal recognition.
