Depending on who you choose to believe, the Skull and Bones secret society at Yale has the skeleton of Geronimo somewhere within the bowels of its sanctum. Allegedly it was George Prescott Bush and some fellow members who raided the grave.
And then there is the old legend that there is a fraternity at UNC Chapel Hill which for well over a century has in its possession a goblet made from the skull of Blackbeard the pirate.
Those very old college frats have some strange stories about them. I wouldn’t doubt many of them were true.
Considering it’s the Skull and Bones and a Bush was involved, I tend to believe it.
Blackbeards skull being possessed by a NC frat is believable since he considered the Carolinas his “garden” where he picked off many merchant ships. He was also killed just off Ocracoke island, NC.
