Graves at Carlisle don’t always have the correct names, markers, dates of death, or birth dates. In the case of Earnest Knocks Off, he has two headstones among the 200 students who are buried at the school. Unfortunately the supporting paper archives are incomplete, which isn’t helpful as tribes demand the return of the remains of students. The question, “When century-old records are lacking, and even headstones can be unreliable, how do you fully account for the dead?” remains.
