Records
Agencies and subagencies were created as administrative offices of the Bureau of Indian Affairs and its predecessors. Their purpose was (and is) to manage Indian affairs with the tribes, to enforce policies, and to assist in maintaining the peace. The names and location of these agencies may have changed, but their purpose remained basically the same. Many of the records of genealogical value (for the tribe and tribal members) were created by and maintained by the agencies.

Many of the historical records of this agency are housed in the Rocky Mountain Regional Archives of the National Archives and Records Administration (NARA) in Denver, Colorado. Records in that collection which may be of assistance to the genealogist include:


 * Records of birth, death, marriages, adoption, and divorce, 1882-1920
 * Land patents, 1914-1918
 * List of Turtle Mountain half breeds, 1881
 * List of allottees, no date
 * List of Assiniboine school children, 1910
 * School census, 1916

Many more records of lesser genealogical value are also in this collection.
