Dear Ms. Matthews,
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 contact the appropriate State archives or historical society to request a search for the birth records of George Topper. Also, please review the FamilySearch Research wiki for United States Birth Records.
We hope this is helpful. Best of luck with your research!
