Lynn Grace Haller, age 83, of Highland, Illinois, passed away peacefully on Sunday, July 6, 2025, at HSHS St. Joseph’s Hospital in Highland.

Born on April 9, 1942, Lynn was the beloved daughter of Alvin and Grace (Zobrist) Knabel. She was deeply rooted and involved in her hometown throughout her life.

On April 4, 1964, Lynn married her childhood friend and lifelong love, Terry O. Haller. Their extraordinary bond began in Sunday School when they were just two years old and blossomed into a loving marriage that spanned more than 61 years. Throughout their life together, they shared countless memories, adventures, and quiet moments of joy. Terry lovingly describes Lynn as “priceless”—a word that perfectly captures the depth of their connection and the immeasurable value she brought to his life.

Lynn graduated from Highland High School in 1960 and earned her nursing degree from Deaconess Nursing School in 1963. With a deep and abiding compassion for others, she dedicated her life to healthcare. She began her career in the emergency room at Highland Hospital, working alongside respected physicians including Drs. Chaney, Wilson, Hediger, Heineman, Fulton, Schuler, and Cantrell.
For a brief time, Lynn explored the corporate world, serving as executive secretary to the Vice President at Purina Mills. Yet her true calling remained in caregiving, and she soon returned to the medical field, continuing her lifelong mission of service and healing.

Lynn’s devotion to her husband, Terry, was unwavering. For the past 25 years, she was his tireless and extraordinary caregiver as he lived with Parkinson’s disease—supporting him with strength, grace, and fierce love until her final hours…..

A dedicated member of the Evangelical United Church of Christ, Lynn was also deeply involved in her community, participating in a local bowling league and golfing with friends. She embraced life with enthusiasm and a spirit of adventure, traveling with Terry to all 50 states and 24 foreign countries. Many of these journeys were made in their beloved vintage Shasta Motorhome and 1948 Willys Jeep, which became symbols of their shared love for the open road. Of all the places she visited, Colorado held a special place in her heart, where she found joy in camping, painting, and canoeing amid the natural beauty.
Lynn had a lifelong passion for genealogy and a deep appreciation for the arts. She studied oil painting under renowned artist Ted Blaylock and found joy in working with pastels—a talent she lovingly shared with her grandchildren. Her artwork earned numerous awards over the years, and she became especially well known for her charming and detailed St. Nicholas paintings.

In her genealogical work, Lynn demonstrated remarkable dedication and skill. She was proficient in reading and writing Old German, which allowed her to translate many historical documents. Over the years, she compiled extensive research and a rich collection of photographs tracing the various branches of her family tree. Her meticulous work is being donated to the Madison County Historical Society, where it will continue to preserve and share her family's legacy for generations to come.

She is survived by her loving husband, Terry O. Haller of Highland; her children, Tad (Lisa) Haller of Baton Rouge, LA, and Amy (Steven) Frohn of Aviston, IL; her grandchildren, Abigayle (Benjamin) Hahn, Cody (Makayla) Frohn, Catherine (Nicholas) Osborn, Kristen Haller (partner Emme McElveen), and Zane Frohn; and great-grandchildren Braylon, Leni, and Noah Frohn. She is also survived by her sisters-in-law, Donna (Ralph) Korte and Cheryl (Stephen) Porter.

Lynn was preceded in death by her parents, Alvin and Grace Knabel, and her granddaughter, Mary Grace Haller.

Visitation will be held from 4:00 to 7:00 PM on Friday, July 11, 2025, at Spengel-Boulanger Funeral Home in Highland, and from 9:00 to 10:00 AM on Saturday, July 12, 2025, at Evangelical United Church of Christ. A funeral service will follow at 10:00 AM, officiated by Rev. William E. Kapp. Lynn will be laid to rest at Highland City Cemetery.

In lieu of flowers, memorial contributions may be made to the American Parkinson Disease Association or the Louis Latzer Memorial Public Library.
