Forgotten cemetery gets cleanup as centuries-old Maryland church reckons with its history of slavery

A small church cemetery in Bowie, Maryland, which was hidden from history due to years of neglect, has been revealed, and in the process illuminated a dark part of America's history of slavery.

The restoration of the cemetery behind Sacred Heart Chapel has been the result of a major project by volunteers, parishioners and descendants of those buried.

In the 1700s, the Jesuits founded a church and a plantation at the site, where they kept enslaved people, including Kevin Porter's ancestors.
