The NC Digital Heritage Center recently announced they have more than 500,000 yearbook pages online from their partnerships with schools across the country. The yearbooks are in the process of being indexed by volunteers.
A list of students from Mecklenburg County is available here.
To search by name, city, county, year or school, a search form is available here.
