In loving memory of

Jack O'Neil
September 18, 2005 - June 23, 2022

Jack Andrew O'Neil, age 16, of Rochester, MN, passed away on Thursday, June 23, 2022.

Jack was born on September 18, 2005 to Sean and Charis (Mulholland) O'Neil, in Rochester, MN. He was homeschooled and excelled in Algebra. He was accepted in the post-secondary education program at Rochester Technical and Community College where he was planning to focus on mechanics and welding.

One of Jack's most recognizable character traits was his work ethic. He was recruited for his first job when he was just 12 years old. From there, he worked several jobs leading to his current position at Affordable Concrete. Jack had a commitment to excellence that, in just a couple of years, led him to becoming his boss' right hand man.

At an early age, Jack developed a strong sense of patriotism and was drawn to military service. He became involved with several local programs including the Marine Corps boot camp training, Civil Air Patrol Services (where he flew airplanes), and most recently, the Explorers program where he was growing a strong interest in law enforcement.

For fun, Jack loved spending time with his family, sisters and friends. He enjoyed going fishing, taking his dog "Gus" on walks, playing football for Century High School, and one of his favorites, lifting heavy weights at the gym. He also had a love for cars, motorcycles, and anything with wheels.

He was a young man who carried himself with great honor, strength and integrity. A young man who loved God and stood strong in his values and traditions. Jack would often be the one called on to help and he would never hesitate to stop what he was doing to lend his hand.

Jack is survived by his loving parents, Sean and Charis (Mulholland) O'Neil, and his sisters, Olivia and Alexis. Grandparents, Steven and Danice (Kocer) Mulholland; Kevin and Teresa (Butler) O'Neil; Great Grandmother, Kaye Cardinal and many aunts, uncles and cousins.

A visitation for Jack will be held Monday, June 27th, 2022 from 8:30-11:00am at Ranfranz and Vine Funeral Home (5421 Royal Pl NW Rochester, MN). A funeral service for Jack will begin at 11:00am following the visitation. Burial will be at Grandview Memorial Gardens in Rochester, MN.
Ranfranz and Vine Funeral Home is honored to be serving the O'Neil family; to leave a condolence or share a special memory please visit

"Charis and family, My heart breaks with you right now. My memory of hiking with you guys and losing Liam and Jack somewhere on the trail, only to find them later with pocketknives in-hand, (the ones Liam wasn't supposed to have along), "chopping" down some tree... my sweet friend, there are no words, but I pray for your healing and the comfort only He can provide. Love, Amy"

"Charis, Sean, Olivia, and Lexi, I am so sorry for your loss! Jack was an amazing young man, so full of energy and ideas. And what a hard worker at Ren Fest! Once Charis asked me to pick him up at the airport after civil air patrol, and I was honored. All our theatre families were constantly juggling kids, schedules, car rides; I remember those days when we behaved as one huge extended family, and anyone's kid was everyone's kid. Jack talked more to me on that car ride home than ever before or since--he had found his passion. He was always doing unique things, getting off the main path, learning with his hands. I am sorry that his time was cut short. Love, Pam"

"Danice--Jack's passing is shocking and tragic for the whole family. Know that Kocers from every branch of the family are thinking of you all, wishing you didn't have to go through this. Peace and healing to you all! Cousin Lynn (Silhasek) Baumert"

"I realized recently just what sort of man Jack was becoming. He worked hard, and was a joy to be around. Throughout my time at Words Players he cared. He always did care for those around him. I wish he had more time than was given to him."

"The kids have so many good memories they've been sharing about Jack. One of Obie's favorite was when he caught that huge snapping turtle! They were in awe of him after that. He was so fun and full of life! Serenity said Daved often put them together, because they'd both be a little quiet in a group, so on their own they'd have to get out of their comfort zone. I'll never forget how cute him and Serenity were in the one act play and had to act like an old fighting couple. -Shauna"

"I remember that first year at Fest, how he and the twins conned so much from people coming through the forest. It was so awesome! Such a fun and great group of kids!?? Ann Hennebeck "
