Hello Marla,
I am looking for a "STanley Petros" from Dietz, wyoming. He is my gg grandfather. He moved his family there, I found in the index of the Sheridan county historian book his name and all that. We know for sure that he worked there and then moved to Montana, but would go back to the mines in the winter and work. He died sometime around 1933 in a coal camp in either Wyoming or Colorado. His daughter remembered the name "Bear Creek coal Camp". WE do not know the location where he was buried. He did have some children born while in dietz too.
