Depending on your genealogical needs, you can either pay to join or access this resource through a library for free. I was surprised to find out that they do have a good amount of information related to North Carolina, especially birth and death dates. There are also census records (including every-name indexes), WWI draft registration cards, and information on Civil War soldiers.

This is probably the most genealogy-friendly ROD website that I have seen. If you have any Duplin County ancestors, you should pay it a visit. And if you don't have any Duplin ancestors, you should still look at it to see what I believe an online ROD should be like. A large portion of my research is indebted to the information provided here. Not only is it attractively presented, but it is also easy to use.

Duplin County, NCGenWeb Project
One of the most active county pages I have seen, Diane Siniard updates the website often. There is a large variety of information on Duplin County and its people, and I check in a couple of times a week to see what's new.

You need to access this website through a library (for free) if you want to look at more than the first page. I have used it exclusively for census records, but there are other features there. Not all of the North Carolina population censuses are online yet, and most are indexed by the head-of- household only.
