Mary Kosek, 68, of Winona, Minnesota, a former Seward County resident, passed away Dec. 14, 2025. She was born May 12, 1957, in Los Angeles, California, and lived a life rooted in love, kindness, and deep devotion to her family.
Mary met the love of her life, Steven Kosek, and they were united in marriage on April 3, 1976. Together, they shared a remarkable partnership and built a beautiful life. They welcomed their daughter, Kristy, on Nov. 18, 1977, and their son, Brandon, on Nov. 6, 1982. Mary was the heart of her family, the most devoted wife, an extraordinary mother, a loving grandmother and a treasured friend to many.
She was known for her fun-loving spirit and outgoing nature, finding joy in walking, bridge, pickleball and golf. Above all else, Mary cherished her family. From 1990 to 2017, Mary and Steve proudly owned and operated a McDonald’s franchise. In retirement, they embraced life fully, enjoying winters in Florida and filling their days with the people and activities they loved most.
Mary was taken from this world far too soon and will be missed beyond measure.
She was preceded in death by her father, Raymond Wynn; her mother, Betty King; step-father, Denver King; and her sister, Connie Geisel.
She is survived by her beloved husband, Steve Kosek; daughter, Kristy Kosek and fiancé Scott Lund; son, Brandon Kosek and wife Brandi; and her cherished grandchildren, Ellie and Thunder, who were the light of her life. Also, lovingly remembered by her brother Ray (Liz) Wynn; sisters, Shelley (Dan) Wynn-Lopez, Debbie (Dave) Sturges, and many nieces and nephews who loved her dearly.
A memorial service was Dec. 21. Memorial contributions are suggested to the American Heart Association.
