In Loving Memory

Mary Maureen Lynch
July 10, 1941 — October 31, 2026
Mary Maureen Lynch, born on July 10, 1941, in Chicago Heights, IL, passed away on October 31, 2026, after a sudden illness. Her life was one of resilience, love, and a touch of humor that brought light to all who knew her.
Mary was the cherished daughter of Michael and Catherine (Brennan) O’Callaghan, who predeceased her. She was also preceded in death by her beloved husband and her brother. Despite these losses, Mary remained a beacon of strength and compassion for her family and friends.
Mary was a devoted mother to her three children: her two sons, Tommy and Douchebag, and her beloved daughter, Queen Kelli. Her legacy lives on through her five grandchildren: Jessica, Shannon, Rebecca, Collin, and Bridget, who all carry a piece of her spirit within them. She also leaves behind one precious great-granddaughter, Mia, and is survived by a large and loving extended family, including her sisters, brothers, nieces, nephews, and her “supposed” Goddaughter, Genevieve.
Mary pursued a career in the medical field, where her nurturing spirit and dedication to helping others shone brightly. With a nursing degree or certificate, she made a significant impact on the lives of those she cared for, embodying the true spirit of compassion and service. Her involvement in various church activities reflected her deep faith and commitment to her community.
Known for her quirky hobby of collecting, Mary found joy in the little things, treasures that told stories and brought smiles. Those who knew her best will remember her for her unique personality, her humor, and the warmth she shared with everyone around her.
A funeral service to honor Mary's life will be held on November 7, 2026, at 10:12 a.m. at that place in Matteson, where family and friends will gather to celebrate the remarkable woman she was.
