Dear Mr. Kurtz,
Thank you for posting your request on History Hub!
The National Archives has custody of records created by the federal government that document tribal nations administered by the Bureau of Indian Affairs (BIA). We searched the National Archives Catalog and located in the Records of the Bureau of Indian Affairs (Record Group 75) the series Letters Received, 1824 - 1880 that contains a file unit titled M234 - Letters Received by the Office of Indian Affairs, 1824-1881 that has the records of letters received by St. Peter’s Agency and the Minnesota Superintendency, 1849-1856 that includes requests, claims, complaints, applications, and petitions from Indians and private citizens. The St. Peters Agency, established in 1819, was the agency responsible for relations with the Indians in present-day Minnesota and part of Iowa. These records have been digitized and can be viewed online using the National Archives catalog. For more information about these records, please contact the National Archives at Washington, DC - Textual Reference (RDT1) at firstname.lastname@example.org.
Due to the continued impact of COVID-19, you may experience a delay in receiving an initial acknowledgment as well as a substantive response to your reference request from RDT1. We apologize for this inconvenience and appreciate your understanding and patience as we balance mission-critical work and the safety of our staff during the pandemic. Please check NARA’s web page about COVID-19 updates for the latest information.
Next, we suggest you review the Minnesota Historical Society resources pertaining to the Dakota peoples of Minnesota. The Dakota People page featured on the Historic Fort Snelling website provides a brief historical overview with suggested secondary readings. Additionally, please see the Minnesota Historical Society Dakota Family History Research Guide for information about primary and secondary sources, photograph collections, census records, church and vital records, and other resources located within their collections. You may wish to contact MNHS for additional information specific to Bloomington.
Finally, we searched online and located the website Dakota Wicohan which is dedicated to preserving the Minnesota Dakota linguistic heritage and contains pertinent information about Dakota history and traditions.
We hope this is helpful. Best of luck with your research!
