Butler's field research in Maryland also influenced her writing of "Kindred". She traveled to the Eastern Shore to Talbot County where she wandered a bit. She also conducted research at the Enoch Pratt Free Library in Baltimore and the Maryland Historical Society. She toured Mount Vernon, the plantation home of America's first president, George Washington. At the time, guides referred to the slaves as "servants" and avoided referring to the estate as a former slave plantation. Butler also spent time reading slave narratives, including the autobiography of Fredrick Douglass, who escaped and became an abolitionist leader. She read many grim accounts, but decided she needed to moderate events in her book in order to attract enough readers.
