Dear Mr. Ross,
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 a record of the marriage in the FamilySearch Historical Record index for “Texas Marriages” and/or contact the Texas County Clerk in the county where the license was issued. Also, please review the FamilySearch Research wiki for Texas Vital Records.
We hope this is helpful. Best of luck with your family research!
