Thank you for posting your request on History Hub!
In regards to information of the sort you are looking for, you may wish to look at vital records, ie birth, death, marriage, divorce records for North Carolina. Vital records are state level records and are not housed at NARA.
Depending on the dates of the records, there are two places where you can begin your research:
The State Archives of North Carolina:
And the NC Division of Public Health
I hope this is helpful in your research!
