Dear Laura Carter,
Thank you for posting your question on History Hub!
The Federal Government does not ordinarily create or maintain birth, adoption, death, marriage or divorce records. Such records are made and kept by State and local governments rather than the National Archives. We suggest searching substitute record sources such as probate records, church records, and newspaper records that may uncover more information about your ancestor.
The vast majority of records in our collection are not name-searchable. For more information on conducting genealogical research within our records, please visit our webpage: https://www.archives.gov/research/genealogy.
We suggest that you review the FamilySearch Research wiki for Arkansas and Louisiana Vital Records https://www.familysearch.org/wiki/en/Arkansas_Vital_Records https://www.familysearch.org/wiki/en/Louisiana_Vital_Records.
We also recommend contacting the Arkansas State Archives as well as the Louisiana State Archives (https://www.arkansasheritage.com/arkansasstatearchives/home ) to inquire if they have additional family records.
We hope this information is helpful in your research!
