I found a death notice for Celestin Aubuchon:
Date: April 09, 1915 Friday
Paper: Anaconda Standard
Celestin Aubuchon one of the best known old-time miners in the Phillipsburg district, died very suddenly Tuesday of heart failure. Mr. Aubuchon was a Canadian, 75 years of age, and had been a resident of Granite and Phillipsburg for more than 35 years. He was born in Quebec, Canada, where he leaves an aged wife and several children. One daughter, Mrs. F.F. Fernet, lives at St. Albert, Alberta, Canada, and visited her father in this city a year ago. The funeral services will take place at 9 o’clock Thursday morning at St. Philip’s Catholic church.
