Good to hear from you.I can't explain the marriage record you found. There isn't anyone by that name in Sampson County that I can locate at this time.I think the certificate could be incorrect. Daniel Ballard Jackson was listed in the WW Draft.This is not your man.He married Nancy Pearl and is listed in the 1930 census as was your Daniel and Bertha. Your Daniel Jackson is in 1920 Federal Census with Bertha. "Ballard" Jackson is in the 1920 census with Pearl. Daniel Washington Jackson is in the WW draft records, listed from Cooper, NC, born 29 June 1891.He was married with two children.I believe this is the Daniel Jackson that married Bertha Carroll.
