Dear Mr. Bernate,
Thank you for posting your request on History Hub!
We searched the National Archives catalog and located Deedbooks, 1792 - 1869 in the Records of the Government of the District of Columbia (Record Group 351). For more information about this series, please contact the National Archives at Washington, DC - Textual Reference (RDT1) at Archives1reference@nara.gov.
We also located the series Letters Received, 1789 - 1906 in the General Records of the Department of State (Record Group 59) that includes the file unit January THRU March 1791, 1/1/1791 - 3/31/1791, which contains a Letter from Daniel Carroll to George Washington and the January - February, 1793, 1/1/1793 - 2/28/1793 which contains the digitized Letter from David Burnes to President George Washington. The latter is available digitally using the Catalog. For information about the former, please contact the National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org.
In addition, we located the Maps of Early Washington, DC in the Records of the Coast and Geodetic Survey (Record Group 23) that shows numbered blocks and reservations, street names, and the properties of the original land holders. For more information about these maps, please contact the National Archives at College Park - Cartographic (RDSC) 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, RDT2, and RDSC. We apologize for this inconvenience and appreciate your understanding and patience.
The Library of Congress (LOC) has additional information in The Daniel Carroll Papers. We suggest you review this information. You may need to register with the LOC to request the item. LOC also has a digitized Plan of part of the city of Washington on which is exhibited the division of lots : made under a commission from the High Court of Chancery of the state of Maryland and directed to Dan'l Carroll of Duddington, Thomas Peter, and Nicholas King.
Finally, we located Original Landowners: Washington, DC Genealogy that names the landowners from 1663 to 1703. Please note that the land may have changed hands between 1704 and 1790. Additional deedbooks of Georgetown, Washington, and other areas that became part of the District of Columbia (DC) from Maryland are available at the Maryland State Archives. Deedbooks of Alexandria and Arlington that became part of DC and were returned to Virginia in 1846 are available at the Library of Virginia.
We hope this is helpful. Best of luck with your research!
