I don't know but I think it is around the 1800's
They still exist.
They have existed well into North American prehistory (possibly somewhere between 10000 BC to 5000 BC), as have most Native American tribes.
Members of the Mohawk tribe are still alive today.
Black Kettle became a chief of the Cheyenne in 1854 and almost nothing is known of his life prior to that time. The Cheyenne kept no written records and the origin of the name is uncertain.In Cheyenne it is Mo'ôhtavetoo'o, where the element mo'ohta- means black and -vetoo'o- is a pan or cooking pot in the So'taa'e dialect.A black cooking pot can only be an iron one obtained from white traders; perhaps at the time he was born (around 1803) such things were new and unfamiliar to the Cheyenne, so he may have been named for one of the earliest iron pans among his band of the tribe.
The actual Cheyenne tribe split from other Algonquin speaking nations located in the Great Lakes region around 1500 AD and began migrating west. They settled eventually in the Dakotas, and became a unified tribe in the early 19th century.
Geisha began around the year 1589, and have continued with their practices and traditions to the present day. So, they still exist in this time period as well.
The Cheyenne people actually spoke their own language (Tsėhesenėstsestotse). It's part of the Algonquian language family (specifically Plains Algonquian, which also includes Arapaho_languageand Blackfoot_language), and is distinct from the Siouan languages spoken by the Dakota, Lakota, and other Plains tribes.

The Cheyenne tribe lived in Minnesota at the time of first European contact. Then they moved to the Dakotas and adopted horse culture.

then and now
The Cheyenne tribe is thought to have emerged from Algonquian stock around the Great Lakes at some time around 1500, gradually moving westwards due to pressure from the Assiniboin. They did not encounter Europeans ("first contact") until about 1650 when some Cheyenne visited the French settlement at Fort Crevecoeur, near the later Chicago. The French had no way of estimating how many people were in the Cheyenne tribe, since they only met a few of them. Clearly, any attempt at giving a population figure for the 1500s must be entirely guesswork, since there is no evidence or record of the tribe at that time; one study gives a figure of 3,500 but this must be regarded as unreliable.
