In the record

C. C. Royce’s 1899 schedule records 3 cessions of land from Northern Cheyenne: about 28 million acres by this atlas’s estimate, counting overlaps once. 2 of them came through acts of Congress. The largest was Land of the Arapaho, Northern Cheyenne and others in several states, ceded 1876 (area 597), about 21 million acres, ceded under Treaty of Fort Laramie (1868), Lakota (Sioux) and Arapaho.

The atlas records 1 broken treaty promise involving Northern Cheyenne: Fort Wise (1861), Sand Creek (1864) and the Little Arkansas reparations (1865).

The records group it with Cheyenne. Today, Northern Cheyenne Tribe of the Northern Cheyenne Indian Reservation, Montana carries this history, as their own pages or research records say.
