With respect to enrollment in Rocky Boy, because the reservation was established by an Act of Congress for "Rocky Boy's Band of Chippewa Indians and such other homeless Indians," the language of the law was intended in 1908 by Chief Rocky Boy and Thralls B. Wheat, to leave the door to enrollment open to his brethren who were away on a hunt at the time of the Wheat Census. <Chippewa oral history of the Robert Gopher family>. The Chief Big Rock family were away as was often done, Chippewa bands separate during hunting excursions, hunting in western Montana. Because they were not directly enumerated in the Wheat census, Chief Rocky Boy inserted the language of the Act to include Big Rock's extended family. The language of the Act was not intended to include anyone other than the whole Rocky Boy band, and was limited to Big Rock's family. Ironically, Big Rock is listed on the 1917 McLaughlin census. Chief Big Rock's place of birth is listed as Red Lake, Minnesota. This is the true and legitimate successor to Chief Rocky Boy. Some oral history has indicated Big Rock was Chief Rocky Boy's brother, moreover, Chippewa have held Big Rock to be the main "ogemaw" and Rocky Boy was more of a spokesman to him, or a sub-chief. Only the present day Bearwalker family line are the living descendants of Chief Big Rock. After Little Bear took over the affairs of the soon to be established reservation, and the flight to Chief Mountain—Big Rock's family perished on Chief Mountain, from the combined effects of tuberculosis and starvation.
