Dear Mr. Riggs,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Applications for Enrollment in the Five Civilized Tribes, 1898 - 1914 (also known as the Dawes Rolls) in the Records of the Bureau of Indian Affairs (Record Group 75) that may include [Name of Tribal Member]. Most of these records have been digitized and are available using the Catalog. For more information about the non-digitized records, please contact the National Archives at Fort Worth (RM-FW) at email@example.com.
We suggest that you review the NARA web page for Dawes Rolls as an overview of how to research that resource.
We hope this is helpful. Best of luck with your research!
