PENNSYLVANIA: The Irish-immigrant railroad workers were all but forgotten, buried in a mass, unmarked grave in 1832. Railroad documents state that all 57 young men died of cholera, but now a team of historians and other researchers has found the grave—along with evidence that the story of these deaths might not be on the up-and-up. Some of the first bodies excavated show signs of having met extremely violent ends at a time when anti-Irish sentiment was high.
