I received such few responses; I figured I would give it another try. In the History of Berks county I read of a mine explosion on June 21, 1879 in Emaus, Pa. Since this involved my husbands g-grandfather and I would like more information about this disaster. I have looked in the library and have not found anything. Do you have some advice on finding such a thing? Was this a coal mine or some other? Is there a book or e-mail address of such disasters? Thank you for what ever help you can give me? Lillian
