According to the 1958 Anaconda City Directory, page 189:
JACKSON, Fred A. (Ann); janitor--Anaconda Company; householder E. 414 E. Commercial
Ave.
I do remember this family. The oldest daughter was named Ruth (who died a few years ago) and she had a younger sister (in my class which graduated from Anaconda High School in 1957) named Bernice. I believe that Bernice lives in Seattle, but I don't know what her married name is. And they may have had a younger brother named Freddie. I remember that there were lots of kids in the family, and I still think of them everytime I pass by their old home on E. Commercial Street. I will see if I can find out more for you, but I can't do this until after June 15th, as I am going to be out-of-state.
