BTW, I do not have any legal documents except the 1790 census that says he is in Brunswick County, NC.
Dear Ms. Everhart,
We suggest that you contact the North Carolina State Archives, North Carolina State Library and Colonial Records of North Carolina to request a search of their colonial and early state records such as tax lists, land patents, church records, and court papers for information about your Dublin, North Carolina ancestor using all possible name variants. Also, please review the FamilySearch Research wikis for Duplin County, North Carolina Genealogy and North Carolina Colonial Records.
We also suggest that you review NARA’s Resources for Genealogists, as well as the History Hub Blog titled Suggestions and Advice for Family History Researchers. Also, the FamilySearch Research wiki for North Carolina may be useful.
We hope this is helpful. Best of luck with your family research!
