I have the "NORTH CAROLINA Extant Voter Registrations of 1867"
book if anyone would be interested in a lookup to see if
there ancestor is listed as having registered in 1867
to vote. The following counties in North Carolina
are the only ones that are listed: Carteret, Chowan, Clay,
Cleveland, Craven, Cumberland, Currituck, Davidson, Duplin,
Edgecombe, Franklin, Gaston, Granville, Guilford, Hyde, Onslow and Wake.

Here are two excerpts from the introduction to the book giving an
explanation to its contents:

"These voting lists were to have been made up of all males, age
twenty-one and over, who had lived in the precinct for one year or more. The registrars had to sign the oath of allegiance and had to be assured that the registrant had not given aid and comfort to the enemy, the Confederate government. Many People were not allowed to vote for any number of reasons...."

"The voter lists found in the papers of the Secretary of State in the Archives of North Carolina in Raleigh that comprise this book are the only lists that have been found to date, either there or in the papers of the Second Military District of Charleston in the National Archives. The whereabouts of other lists are unknown at either repository. Even though we do not have the lists for the entire state, the lists are historically interesting because it is the first showing of full names of black voters, many of whom were former slaves and give for some a record of residence and an indications of age."

The list only indicates the name of the person, whether they were accepted or rejected, county, precinct and race.
