Ancestry.com adds American Indian censuses to its US Deluxe subscription.
If you're having trouble finding American Indian ancestors, you'll be glad to learn reservations took annual censuses between 1885 and 1940 at the behest of the federal government — and Ancestry.com has added those records to its US Deluxe subscription ($179.40 per year).
You can search by name, tribe, birth date, family members and other parameters. Those census rolls, also on microfilm M595 at the National Archives and Records Administration (NARA) <archives.gov>, serve as a good starting place for genealogists investigating American Indian ancestry. (To use the film, you have to know what tribe your ancestor belonged to.)
