Dear Ms. Ballard,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Ledgers, 1791 - 1907 in the Records of the Office of Public Buildings and Public Parks of the National Capital (Record Group 42) that may indicate payments to Peter Brown during his service at the White House. For access and assistance in searching these series, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at email@example.com.
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 RDT1. We apologize for this inconvenience and appreciate your understanding and patience.
We also searched the Library of Congress and located the James Buchanan and Harriet Lane Johnston Papers, the Abraham Lincoln Papers at the Library of Congress and the Ulysses S. Grant Papers that may contain information regarding Peter Brown.
Lastly, we searched the Internet Archive and located the book “Abraham Lincoln's servants and employees” that contains a reference to Peter Brown on page 12. The book titled At Work in the Lincoln White House may contain additional references and source information regarding Peter Brown.
We hope this is helpful. Best of luck with your research!
