Do you know if the people you mentioned died in Bladen County or elsewhere?
If they died in Wilmington, try www.onhgs.org
, click on links, and then click on New Hanover County, NC vital records for births, deaths and marriages.
My contact in Wilmington has been Beverly Tetterton and Joseph Sheppard in the NC Room, 2nd. floor. Public Library..I think the address is 201 Chestnut St. Wilmington, NC. 28401
