Not sure about the ties of what nationality the coal miners were. Mine were all German and I think one of the effects the coal mines had was the dirt. My dad and all my Uncles were the cleanest men I ever knew, about their body and homes. They all had spent maybe a year or two in the mines during the 30's before they escaped to other jobs. However there was a large feeling toward the Germans after WW2, which I felt. We were chased and had rocks thrown at us on our way from the Lutheran School there in Troy. I just wonder if there is any published material on this period of history?
