A few years ago, people touring the Owens-Thomas House and Slave Quarters in Savannah, Ga., would have heard a lot about George Owens, the lawyer, farmer and Congressional representative who lived in the massive neoclassical home in 1833. And about banker and slave trader Richard Richardson, for whom the house was built in 1816. They might have heard Emma Katin’s name, but not about how the enslaved black woman spent most of her nights sleeping on the wooden floors of the house, so that she could be available at all hours to the infants in the Owens family.

They wouldn’t have heard about the 14 other enslaved people who lived there. And there’s a good chance that guests would not have heard about the 400 other slaves the Owenses had on their other nearby properties.

“Those pieces of the story would have been missing because she would have been treated as an accessory to the Owens’ lives,” said Shannon Browning-Mullis, a curator of history and decorative arts for Telfair Museums, which owns the house and has been in charge of rethinking the way its history is told.

In cities including Savannah and Charleston, S.C., where Confederate statues, elegant mansions and plantation weddings are common, tourism has often taken the form of nostalgia for the antebellum South, Southern charm and Southern hospitality. For years, tours of historic homes would focus on their architecture and fine furniture, but not on how the wealth so clearly displayed depended on enslaved labor.
