Looking for information on a Joseph (Joe) Lortie (Lortis) who came from Canada to work in the Butte mine. He would have came around 1882-83 from Ontario. He never married. I located him in the 1910 census for Butte-Silver Bow and in the city directories, up to the year 1917, then lost him. Wondering if anyone knows where I can find information on the 168 miners who died in the Butte mining accident in 1917.
