Mary Elizabeth Peterson

May 24, 1935 — January 18, 2021

Mary Elizabeth Peterson, age 85, passed away on January 18, 2021 at Lake View Care Center in Bigfork, MT. She was born in Bountiful, UT, on May 25, 1935. Mary was the third of four children born to Robert W. and Halleen Nicol.

In 1950, Mary met and married the love of her life, Harold “Sonny” Ray Peterson. In 1958, the family, which now included three children, moved to Long Beach, CA and in 1971, they moved to Riverside, CA. Mary worked as a Patient Greeter at Beaver Medical Clinic in Redlands, CA. In 2002, Mary and Sonny retired in Polson, MT.

Mary was one of God’s special earth Angels. She was a kind and giving soul that would do anything for anyone. She had a great sense of humor, was a wonderful cook (especially pancakes and oatmeal cookies) and she always made you eat whenever you visited. Mary enjoyed traveling, animals, movies, and visiting with friends. She was a member of the Church of Jesus Christ of the Latter-day Saints and the Red Hat Society. Mary was truly selfless, had a caring and compassionate heart, and was full of unconditional love.

Mary is survived by her daughter, Vicky (Gene) Siwy of Needles, CA; son, Kent (Domenica) Peterson of Bigfork, MT; five grandchildren, four great grandchildren, and three great-great grandchildren; sister, Sally (Wayne) Smith of Riverside, CA; and many nieces and nephews.

She is preceded in death by her husband, Sonny; daughter, Patricia; parents, Robert W. and Halleen Nicol; brother, Robert J. Nicol; and sister, Nancy Argyle.
