Yesterday, I visited the Schuylkill County Archives, perusing the Molly Maguire files. I come across testimony regarding my Great, Great Grandfather, Francis Boyle. Apparently, on the 4th of July, 1875, he and Barney Boyle went to the field next to the High School in Lansford, PA and set off rounds from a "cannon" (actually, a small powder tester, as shown). They did it so much, that the cannon eventually broke! Neat little story, that I never knew!
