For general advice, we suggest reading the web page How to Begin Genealogical Research, the History Hub blogs Suggestions and Advice for Family History Researchers and You Want to Find Out About an Indian Ancestor, and the FamilySearch Blog Beginning Genealogy: How to Get Started the Right Way.
The Bureau of Indian Affairs has a webpage on Tracing American Indian and Alaska Native Ancestry, the Department of the Interior has a page on Trace Indian Ancestry.
We suggest that you review the National Archives’ web pages Resources for Genealogists and American Indian and Alaska Native Records in the National Archives.
Additional guidance and lists of resources are provided on the Archives Library Information Center Genealogy page, the FamilySearch Research wiki pages for United States Genealogy, and United States Indigenous Peoples, the Library of Congress pages on Frequently Asked Questions: Local History & Genealogy and Local History and Genealogy Research Guides, and the webpage of the National Genealogical Society.
If you were to provide more specific information about the specific people you are researching and what types of records you are seeking, there may be persons in our community who are able to provide you with more specific advice.
