Jamie, I think Quantrill may have given out that story after he left for Kentucky where he rode some with Sue Mundy... His skull from 1905 to 1942, was part of a fraternity initiation rite in Dover Ohio, a candle lit ceremony where inductees would touch the skull, and then dip their hand into a cauldron of molten lead (hot water coated with aluminum powder paint). In 1972, an aging alumnus of the fraternity donated the head to the Dover Historical Society. Here as Paul Harvey would say is the rest of the story.
