When it became a state in 1821, Missouri had a Native American population estimated at around 20,000. Native peoples within the state included the Kickapoo, Shawnee, Ioway, Otoe, Delaware, and Osage. Most of these nations had been driven to Missouri from the east by growing numbers of white inhabitants. The territory of the Osage, the most powerful tribe, included land in present-day Missouri, Kansas, Oklahoma, and Arkansas. But in an 1808 treaty the Osage had given up most of their land in southern Missouri Territory, believing the treaty permitted them to continue hunting and fishing in this region.
By the 1830s most Native Americans had been pushed out of Missouri. Many tribes passed through the state on their way west to the Indian Territory during the forced relocations of the 1830s, including the Cherokees on their tragic journey along the Trail of Tears.

Some people want to become enrolled members of a federally recognized tribe. Others want to verify a family tradition (belief, fact or fiction, passed from generation to generation) that they descended from an American Indian, either in their distant or near past. While others might want just to learn more about from whom and where they came.
When establishing descent from an Indian tribe for membership and enrollment purposes, the individual must provide genealogical documentation. The documentation must prove that the individual lineally descends from an ancestor who was a member of the federally recognized tribe from which the individual claims descent. Read more...

The National Indian Law Library provides a variety of guides with documents and links to help those conducting research on Native American ancestry. They do not provide personal assistance with tracing ancestry.

Jefferson College Library is a congressionally designated selective depository for U.S. Government documents. Public access to the government documents collection is guaranteed by public law (U.S.C. Title 44, Sections 1710 and 1711).
The Federal Depository Library Program was established by Congress to ensure that the American public has access to its Government’s information. GPO administers the FDLP on behalf of the participating libraries and the public. Information products from the Federal Government are disseminated to these nationwide libraries that, in turn, ensure the American public has free access to the materials, both in print and online. The official version of govinfo.gov launched in December 2018 and was developed to provide free access to government information from all three branches of the Federal Government.
Access to the print collection and use of our public access computers are both available during all hours of operation. Chat reference assistance is available during additional evening, weekend, and holiday hours. For a list of days closed, regular, chat, and special hours see our HOURS page.
The Bureau of Indian Affairs has a variety of resources for those interested in establishing American Indian or Alaska Native ancestry.
