In 1927, Sacramento Bureau of Indian Affairs Superintendent Lafayette A. Dorrington was instructed by Assistant Commissioner E. B. Merritt in Washington D.C. to list tribes in California that Congress had not yet purchased land to be used as reservations. As part of the 1928 California Indian Jurisdictional Act enrollment, Native Americans were asked to identify their “Tribe or Band.” The majority of applicants supplied the name of the mission that they knew their ancestors were associated with. The enrollment was part of a plan to provide reservation lands promised but never fulfilled by 18 non-ratified treaties made in 1851-1852.
