September 6, 1930 – January 28, 2026
Isabelle R. Olson, 95 years old of Kenosha, WI, passed away on Wednesday, January 28, 2026, at her home.
She was born September 6, 1930, in Kenosha, WI, the daughter of the late Frank and Sophie (Augustine) Trotta. Isabelle attended Bain School, McKinley Middle School, Kenosha High School, and Gateway Technical College.
On August 26, 1950, she married S. Robert Olson at Our Lady of Mt. Carmel Catholic Church, and he preceded her in death in 2004.
Isabelle was a parishioner of Our Lady of the Holy Rosary of Pompeii Catholic Church, Kenosha, where she was the past president of the Holy Rosary Ladies Society, taught religious education, and served as a lector for 37 years. She also volunteered at the church festival for many years and sewed the altar vestments.
She stayed home and raised their four daughters, and was a seamstress for many family members and friends during that time. In 1974, she started employment at the Society for the Preservation of Barbershop Quartet Singing in America, retiring in March of 2004. During her time with the society, she worked in the merchandise department and attended many conventions in the United States and Canada. Isabelle enjoyed cooking, baking, going to Las Vegas, playing Bingo and cards, and especially being with family and friends.
