It might be possible to identify some slave holders by correlating the 1835 Cherokee census, which did identify them, with the 1851 Drennan Roll which enumerated people by the district where they resided, and the 1860 U.S. Census Slave Schedule which also enumerated by district. Many of the people who are on the 1835 census had died by 1851 (or 1860) or were not living in the Cherokee Nation at the time, so obviously there are big gaps, but some names do carry through all three counts.
