The Diocese has no records explaining why graves in this wooded lot were placed away from the church's burial lot. Possibilities include that the families were not Catholic, had unknown religious orientation, or were not baptized. Generations of self-report conclude that the unmarked graves at the back of the lot were associated with the tannery in Thorndale. The lack of formal headstone markers may be due to the workers being too poor, not Catholic, or the result of mass burial during an epidemic.
