Dear Ms. McQuade,
Thank you for posting your request on History Hub!
The Federal Government does not ordinarily create or maintain birth, death, marriage or divorce records. Such records are made and kept by State and local governments rather than the National Archives. We suggest that you search for records of the marriage in the FamilySearch Virginia Marriages, 1785-1940 index, the Library of Virginia’s Marriage Records Index Collection, 1719-1898 and/or contact the Virginia Department of Health’s Office of Vital Records for a record search. We also suggest that you review the FamilySearch research wiki for Virginia Vital Records.
We hope this is helpful. Best of luck with your research!
