Mary Elizabeth Tun

Mary Elizabeth Tun, of O’Fallon, Missouri, passed away peacefully on November 9, 2026, surrounded by loving thoughts. She was born on April 27, 1945, in Saint Louis, Missouri, and will be remembered as a giving, generous, kind, and loving woman whose sweet nature, good sense of humor, and playful, goofy spirit brought joy to the people around her. She was truly one of a kind.

Mary built a life centered on devotion to her family, steady work, and simple joys that became lasting memories for those who knew her. She worked at Venture and later at K-Mart as a bookkeeper in North County, Missouri. Outside of work, she found happiness in reading, cooking, doing puzzles, coloring, and spending time with her family. She also gave generously of herself in her community, coaching sports and helping at the little league park. One especially cherished memory is of Mary coaching softball alongside her husband for their daughter’s teams, a reflection of the love and encouragement she poured into her family’s lives.

Among Mary’s proudest accomplishments were her 50-year marriage to her beloved husband, Bob, and the family they built together. Her children, grandchildren, and great-grandchild were a deep source of pride and happiness, and her love for them was evident in all that she did.

She is survived by her daughter, Debra Scheer and Debra’s husband, Michael; by her daughter-in-law, Kim Tun; by her grandchildren, Jolie Scheer, Josie Scheer, Trey Tun, Tommy Tun, Hunter Tun, and Arlene Cain and her husband, Luke; and by her great-granddaughter, Delaney Cain. She is also lovingly remembered by her brothers, William Miskelly, Tom Miskelly and his wife, Joan, and Mike Miskelly and his wife, Ty; her sister-in-law, Cindie Miskelly and by her furry companion, Max, a beloved lab. She will be greatly missed by many other family members and friends whose lives were brightened by her kindness and love.

Mary was preceded in death by her husband, Robert “Bob” Tun, Sr.; her son, Robert “Bobby” Tun, Jr.; her parents, William and Edna Miskelly; and her brother, Eddie Miskelly. Those who loved her carry forward the warmth of her presence, the laughter she so easily shared, and the example of a life lived with generosity, sweetness, and heart.
