Tony Burroughs, CEO of Chicago’s Center for Black Genealogy, bends to take a photo at the gravesite of his great-grandparents in the Oakridge Cemetery in Hillside. “I realized they were right under my feet,” he says. “I can resurrect my ancestors that are not in history books but they live. They survive….And it’s up to me to tell their stories.” Charles Rex Arbogast / AP As a child, Linda Davis and her mother broke clay pots over the graves of their ancestors, letting the flowers in the pots take root.
