A number of African American cemeteries in the Tampa Bay, Florida, area have been "lost" or "erased" over time. One cemetery, the Zion Cemetery, has been the focus of a great deal of scrutiny. Ground Penetrating Radar (GPR) has been used to verify the presence of graves. Government and community members have gotten involved to identify those interred there, and to learn more about them.
Drew Smith is the Genealogy Librarian at the University of South Florida Libraries and he is leading a group of volunteers to trace the families and descendants of those interred in the Zion Cemetery.
