Flathead Indian Agency (Montana)
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:
- Census rolls, 1913-1940
- School censuses, 1912-1943
- Day and boarding schools attendance reports, 1899-1917
Many more records of lesser genealogical value are also in this collection.
