Dear Ms. Woodmansee,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Population Schedules for the 1830 Census, the Population Schedules for the 1840 Census, the Population Schedules for the 1850 Census, the Population Schedules for the 1860 Census, the Population Schedules for the 1870 Census, and the Population Schedules for the 1880 Census in the Records of the Bureau of the Census (Record Group 29) that may contain information about Robert Burns living with his wife Mariah and/or children in Ohio. Mariah’s race is listed as white. For more information about the non-digitized schedules, 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.
You may wish to search Ancestry or FamilySearch for the U.S. Census. There may be a fee for using Ancestry. Instead, please check for access at your local library as many library systems subscribe to these sites, making them free for their patrons.
We suggest that you begin by talking to your various family members, especially the more senior ones, and ask them questions so you can gather names, dates, places, and stories. With that information in hand, you may begin to gather records about these family members and the places associated with them. In addition, NARA Native American Heritage webpage, NARA Resources for Genealogists webpage, and the FamilySearch Research wiki for Indigenous Peoples of the United States Genealogy may be useful.
We also suggest that you contact The Library of Virginia for any resources in their holdings about Native Americans; and the State Archives of Ohio to request a copy of her death certificate that will also indicate her race.
We hope this is helpful. Best of luck with your family research!
