Tammy Gibson wants you to visit the gravesites of your deceased relatives.

“Have you checked on your ancestors?” said Gibson, the founder of Sankofa TravelHer, an organization dedicated to honoring the legacy of African-Americans who were often denied dignity in death.

As we learned last episode, Chicago’s long history of segregation affected both the living and the dead, as many area cemeteries once offered burial space “for the exclusive use of the Caucasian race.”

So where did African-Americans bury their loved ones in the 19th and early 20th centuries?

“From my research, African-Americans could not get buried in Chicago,” Gibson told Curious City. Instead, she said many African-Americans buried their dead in the South Suburbs, at cemeteries like Mount Glenwood in Glenwood, Ill., and later Burr Oak Cemetery in Alsip, Ill.

In this episode, Gibson tells us about the people who first started these cemeteries and the notable people buried there. She talks about the work she does to continue honoring the deceased, including offering a reinterment ceremony years after the 2009 grave-stacking scandal at Burr Oak Cemetery. Gibson also works to get headstones for notable Chicagoans who do not have them. This includes Eugene Williams, whose death sparked the 1919 Chicago Race Riot, and journalist Ethel Payne from Chicago’s Englewood neighborhood, who was known as the First Lady of the Black Press.
