My Grandfather Steven Kruzelak was born and raised in Helvetia, started working in the mines around 7 years of age. Lots of history was lost in the fire. I lived there in the early 90's, loved walking around those hills. I now own a "Coal patch Double house" in Adrian Mines (Delancey) I also have ancestors from here early 1900's I love learning the history. A really neat book about life in Helvetia is......
