Dear Ms. Schmidt,
Thank you for posting your request on History Hub!
We suggest that you begin by assembling as much of your family tree as possible, as far back as you can go and see if any ancestors can be located on early census rolls. Members of the three Shawnee tribes who were relocated onto reservations would have been enumerated in the Dawes Rolls. For an overview on how to begin, please review NARA’s Resources for Genealogists and Native American Heritage as well as the FamilySearch Research wiki for United States Genealogy and Indigenous Peoples of the United States Genealogy.
When embarking on Native American genealogy, please note that the records in the custody of NARA often only detail those living on the reservations or being administered by the Bureau of Indian Affairs. If an ancestor was Native American and left the reservation or did not have interaction with the United States Government as such, they will not be recorded in NARA’s records and tracing their genealogy may be difficult.
We hope this is helpful. Best of luck with your family research!
