Chief Rocky Boy had been under increased pressure to add the Cree and Metis to his rolls by government officials. Even after the reservation was to be created, in the spring of 1916, Frank Bird Linderman met with Chief Big Rock in northside, Great Falls, and other Chippewa tribesmen including Standing Rock, Pat Raspberry, Crazy Boy (Chief Rocky Boy's brother), and Charles Mosney. On his death bed, and his last letter to Frank B. Linderman, Rocky Boy stated "I don't know if I will ever see you again, Little Bear (referring to their inclusion, along with Metis led by Kennawash)... is trying to get them all in. It is up to my band of Chippewa Indians to let them in." Rocky Boy's understanding of the working of tribal sovereignty is correct. <Worchester v. Georgia, 31 U.S. (6 Pet.) 515 (1832)>.
