Obituary

MCFARLAND - John Thomas O'Connor, age 66, of McFarland, passed away on Wednesday, June 10, 2026. He was born on April 29, 1960, in Minneapolis, Minn., the son of John "Jack" and Jane (Hultkrans) O'Connor. The family lived in St. Paul until John was 11, then moved to Rockford, Ill.  In 1995 John moved to Madison.


John graduated from Boylan Catholic High School in Rockford, Ill., and later earned his bachelor’s degree from Northern Illinois University. During Syttende Mai weekend, he met the love of his life, Sandra McTavish. The couple married on May 27, 2000, at Tyrol Basin in Mount Horeb. John worked as a teacher’s aide for the McFarland School District retiring in 2024.


John had a lifelong passion for skiing and looked forward to every opportunity to hit the slopes. Some of his favorite destinations included Snowriver Resort in Michigan's Upper Peninsula and the slopes of Lutsen, Minn. A master at finding the best deals on ski equipment, he also enjoyed organizing annual ski trips with friends, often planning them around Super Bowl weekend.


An expert planner, John loved arranging family vacations, weekend getaways and road trips, carefully attending to every detail. He treasured family camping trips and creating lasting memories with those he loved. In his retirement he enjoyed planning trips with friends.


John's larger-than-life personality made a lasting impression on everyone he met. He had a remarkable ability to make people feel comfortable and welcomed, and he truly never met a stranger. Whether traveling, attending events, or simply running errands, John had a gift for striking up conversations and making new friends wherever he went.


John was deeply involved in his community and his sons' activities. He volunteered at high school football games, working the chain crew, and was always eager to support school events and activities. His family was the center of his world, and his sons were his greatest pride and joy. He was their biggest supporter, loudest cheerleader, and was endlessly proud of the men they became.


A devoted and loyal fan of the Chicago Bears, John stood by his team through every season. He was also known for his quick wit, legendary dad jokes, and never met a  “pun,” that he didn’t like. He never passed up an opportunity to make someone laugh, and his sense of humor brought joy to family, friends, and everyone fortunate enough to know him.



John is survived by his wife, Sandra; sons, Sean (Woojeong Shin) O'Connor and Jack O'Connor; sisters, Susan Stevens, Connie (Richard) Jirak and Mary (Gavin) Brandt; and brother, Vince (Lynn) O'Connor. He was preceded in death by his parents, Jack and Jane; and sister, Mollie O'Connor.


In honor of John, we encourage guests to wear a Hawaiian shirt or something green as a tribute to his life and spirit.

I am heartbroken to hear this news. John was a wonderful man. During his time as a special needs aide, he was one of few people in the district that truly connected with our son and Calvin adored him. We are so very sorry to your entire family for the loss of such a kind and special person. Pam, Jeff, & Calvin Aerts

I had the privilege of working with John a few times at MPS over the years. He had such a gift for connecting with students, treating everyone with such kindness, compassion, and respect. The kids adored him. He always had a smile, a kind word, a funny story, or a joke to share. He made such a positive impact on so many lives. Rest well, John. You will be missed. My deepest condolences to his family and friends.

Sandra, Sean, and Jack, We are very sorry for your loss. We are a family from Troop 53 and have wonderful memories of John's contributions to the troop. He brought his outgoing personality to the role of Popcorn kernel, and the scouts sold more popcorn than ever. I remember his kindness and laughter at numerous troop events, including at Lambeau Field. I wish you all peace and warm memories. Sincerely, Kris Whitman, Mark and Blake Johnson

I'm so sorry to hear of Johns passing. I first met John at Northern Illinois University in the early 1980's We both played for the NIU Rugby team in the position of second row. John was always one of those stand out individuals that everyone knew and respected and was always up for a little tom foolery! You will be missed my friend! With you!!!
