Mary Louise Fennell
Mary Lou Fennell, of Sioux City, Iowa, passed away on Monday, May 25, 2026, at her home, surrounded by love. She was 72. Visitation with the family will be Friday, June 5, 2026, from 5:00 to 7:00 PM with a Prayer Service at 6:00 PM. Memorial Service will be Saturday, June 6, 2026, at 11:00 AM at First Lutheran Church (3939 Cheyenne Blvd, Sioux City).
Mary Lou was born in Sioux City to Thomas Fennell and Irene (Dougherty) Fennell. She attended Blessed Sacrament School until the family moved to Huron, South Dakota. After a few years there, they landed in Omaha, Nebraska. Then the family finally settled in Pierre, South Dakota, when she was in high school. She graduated from T.F. Riggs High School in 1973. She married Kirby Hedman in 1976; they went on to have two daughters, Elizabeth and Alisha. After their divorce, Mary Lou moved her and the girls to Madison, South Dakota, where she enrolled in classes at Dakota State University. She graduated in 1992, the first of her siblings to do so, and moved back to Pierre where she began working at St. Mary’s Hospital. She remained there until 1997, when she returned to Sioux City to help support her dad, Tom, after the passing of her mom, Irene. She had a long career at Mercy Medical Center, where she formed strong relationships with great coworkers.
Mary Lou loved her family fiercely, especially her grandchildren. They were the light of her life, and she loved spending time with them and cheering them on. Her friends and family were everything to her. She loved traveling, as long as it was to see loved ones – always ready for a good time. She was everyone’s favorite aunt, making those around her feel special. She had some wonderful family vacations to Tom and Tracy’s cabin in Colorado. She finally saw the Grand Canyon, through a trip organized by Alisha. Mom’s greatest gift was her ability to love people unconditionally, which we will all be eternally grateful for experiencing. The impact she had on the people around her is evident in her long-lasting friendships; from her year in Omaha making lifelong bonds, her Pierre High Schools friends, her Hayes farmwife friends, the apartment family and her Divorce Mafia group from Madison, her Condo Crew, her Girls’ Weekend, and many others. She had an incredible village who loved her as fiercely as she loved them.
Grateful having shared her life are her two daughters, Elizabeth Walz (Mark) of Sioux City and Alisha Bernardy (Luke) of Terrill, Iowa; grandchildren, Emma, Elliot, and Ethan Walz; Quinn, Deacon, Owen, and Kyran Bernardy; sisters, Maureen Shepherd (Ray) of Brookings, South Dakota, and Micki Ritter (Dave) of Vail, Arizona; brother, TJ Fennell (Luisa) of Sioux City; nephews, Todd Meyers (Dawn), Brian Schwanz, Chris Shepherd (Heidi), Andy Meyers (Kayleen), Tom Meyers (Tracy), and Devin O’Day (Brittany); nieces, Sarah Schulte (Dan) and Megann Kjolsrud (Mark); Al and Yvette Thomas, Karla Hedman, Susan Culberson, Julie Titus, Terri Sauter, Jaque Conrad, lots of Nelson, Dougherty, and Fennell cousins; as well as many friends. She was preceded in death by her parents, Tom and Irene Fennell; sister, Kathy Fennel; and sister, Colleen Schwanz.
