She was a member of St. Francis Xavier Catholic Church, De Pere, for over 50 years, where she was very active in the Altar Rosary Society and was the funeral lunch coordinator and server for 30 years.

She was devoted to praying the rosary and a longtime member of the Confraternity of the Holy Rosary Society, proudly not missing the monthly prayer meetings. Her other hobbies were cooking and baking for family and friends, scrapbooking of years gone by, and she also enjoyed traveling. Most of all Marilyn loved spending time with her family, especially her cherished grandson, Cory, and the time they shared.
