Harvard’s published research speculated Drana vanished between 1850 and 1852.

Evidence

“Drana, it should be noted, is not listed in the 1852 slave inventory of Benjamin F. Taylor’s estate, nor have I discovered her name in the many related inventories for local planters and their relatives that I have reviewed; this suggests that either she was sold before 1852 and a record of the sale has not been found, or that she perished at one of Taylor’s slave labor camps sometime between May 1850 and August 1852. She may have been buried in an unmarked grave in the slave section of the old Taylor family graveyard near the corner of Richland and Barnwell Streets in present-day Columbia.” — Tamara Lanier, From These Roots, 794
