Baraboo — Phyllis Heggem Harrison, 85, passed away peacefully in her sleep on January 5, 2026. She was born June 12, 1940.

She was preceded in death by her parents, W. Howard and Helen Heggem. After a difficult early childhood, she was adopted into the Heggem family, where she learned to sail and developed a lifelong love of the outdoors.

Phyllis earned a degree as an X-ray technician from William Jewell College. She and Bob were married in 1964 and lived in Arlington Heights, Illinois, for 50 years, spending many summers in Montello, Wisconsin, before moving to Baraboo, Wisconsin, in 2023.

Phyllis enjoyed music, the outdoors, Bible study, and spending time with friends and family. She shared her faith through music ministry in prisons and nursing homes and was a longtime member of Meadows Christian Fellowship Church in Rolling Meadows, Illinois.

Phyllis was a strong believer in Jesus Christ, and her faith and devotion to her family shaped her life.
