Dear Ms. Carpio,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Population Schedules for the 1860 Census in the Records of the Bureau of the Census (Record Group 29) that includes in the slave census, five slave owners with last name Stovall: AA Stovall from Burleson, TX (4 slaves); Marion Stovall from Beat 12, Rusk Co, TX (7 slaves); John Stovall from Palestine, Anderson Co, TX (2 slaves); John E Stovall from Beat 8, Cherokee Co, Texas (1 slave); and John M Stovall from District 2, Angelina Co, TX (3 slaves). We also searched the Population Schedules for the 1850 Census in Record Group 29 that includes the slave census but were unable to locate slave owners with the last name Stovall. In addition, we located the Population Schedules for the 1870 Census in Record Group 29 that included 27 African Americans with the last name Stovall. For more information about the non-digitized schedules, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at firstname.lastname@example.org.

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 review the National Archives document Federal Records that Help Identify Former Slaves and Slave Owners and also search the Chronicling America: Historic American Newspapers for possible information, since during the slavery period owners often advertised in newspapers about their runaway and fugitive slaves in hopes that citizens, or bounty hunters would would find and return their "property" usually for a reward.
We also suggest searching the Texas Runaway Slave Project at the East Texas Digital Archives at Stephen F. Austin State University, It is a database of runaway slave advertisements, articles and notices from newspapers published in Texas, as well as materials from court records, manuscript collections, and books. It documents more than 2,500 fugitive slaves from Texas. The project is ongoing and new content is regularly added to the webpage.
You may wish to search these websites Texas Census; Resources for African American Genealogy at the Texas State Library & Archives Commission; and early census in Texas TSHA | Census and Census Records - Handbook of Texas for additional information and resources.
We hope this is helpful. Best of luck with your research!
