Dear Jenn Watson:
Thank you for posting your question on History Hub!
A very good pamphlet regarding how to file requests for scrip lands can be found on the NARA site https://www.archives.gov/files/publications/ref-info-papers/rip114.pdf. Page 12, for the War of 1812 might be particularly helpful. The index is on microfilm. 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 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 acknowledgement as well as a substantive response to your reference request from National Archives at Washington, DC - Textual Reference (RDT1). We apologize for this inconvenience and appreciate your understanding and patience.
We hope this information assists you with your research!
