NPR is looking for relatives and descendants of African-American workers who died at the Hawks Nest Tunnel project in Fayette County, West Virginia between 1928 and 1932.

An estimated 764 workers died of silicosis while working on the tunnel. Two-thirds of those workers were African-American — many of whom migrated to West Virginia from states farther south, like Georgia and Alabama.

The deceased were often buried in unmarked graves, and some families were not notified of their loved one's death or given the chance to bring them home.
