Eileene Cecelia Armstrong died on October 5, 2020 in Albuquerque, NM. She was born in Butte, Montana on September 18, 1935 to Ularie and Francis (Weldon) St. Onge. She was raised on ranches near Whitehall (Pipestone) and Butte (Ninemile Hill). She graduated from Butte High School in 1953 and received a teaching degree from Dillon Normal School in 1955. Eileene taught in the Butte Public School system for approximately 6 years followed by 2 years teaching in Reno Nevada. She returned to Montana and married Edwin Stanley Armstrong on June 29, 1963. They settled in Cardwell, began a family and later moved to Dillon in 1968. Eileene continued educating generations of southwest Montanans in the Butte, Whitehall, Dillon and Melrose school systems until retiring at the age of 65. Over a span of 45 years, including a 12-year period during which she substitute taught in Dillon, she was in the classroom for over 35 years. During this time she returned to school as a student and received her Bachelors of Education degree from Western Montana College. During her teaching years she developed deep friendships with numerous educators, including Marlene Savage, Tia Kober, Jackie Erfle, Marcy Busch, and numerous others. She loved children of all ages, but had a special place for the younger ones and children with difficult backgrounds. She was an Irish Catholic from Butte Montana and a lifelong Chicago Bears fan. Despite her very mild manner, she liked to claim her rougher heritage, and occasionally threatened to use it, when necessary.
