Dear Mr. Norris,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Reports of Site Locations, 1837 - 1950 in Records of the Post Office Department, 1773 - 1971 (Record Group 28) which includes the file unit Tennessee: Campbell - Chester. Image 799 is a location form for a post office called Laban, with the name of Bannerville crossed out. We also located Records of Appointment of Postmasters and the Establishment of Post Offices in Record Group 28 which includes Postmaster Appointments for Carter County, Tennessee. Image 9 lists a post office at Laban, with Hattie A. Banner as postmaster, appointed 9 November 1900. The form indicates that the post office was discontinued 2 September 1905, effective 31 October 1905, and that the post office at Shell Creek took over its functions.
We also located Records of the Commissioning and Appointment of Postmasters, 1889 - 1908, Daily Records of the Appointment of Postmasters and of the Establishment, Discontinuance, and Name and Site Changes of Post Offices, 1/1899 - 12/1914, and Records Relating to Post Office Department Appointments, 1905 - 1960 that may have additional information about the establishment and discontinuance of the Laban post office, as well as the appointment of Hattie A. Banner. These records are not available online. For access to these records, please contact the National Archives in Washington, DC - Textual Reference (RDT1) via email at firstname.lastname@example.org.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, 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.
We also searched the Official Register of the United States (published every two years in this time period) and found Hattie A. Banner listed as postmaster for Laban in 1901, 1903, and 1905. The 1899 and 1907 Registers do not list a post office called Laban. Furthermore, the
United States Official Postal Guide for 1900 lists the establishment of the Laban post office in Carter Counter, Tennessee under the heading of “Latest Changes.” The United States Official Postal Guide for 1906 lists Laban under the heading of “Post Offices Discontinued on Account of the Establishment of Rural Free Delivery.”
We hope this information is helpful. Best of luck with your research!
