If you're in Raleigh, why don't you check out the NC State Archives there? They have the Lenoir Co. Marriage Register both the copies and on microfilm. Or you can check with the Olivia Raney History Library, also in Raleigh, which contains many NC records; you can contact them from the info on their website:
