Margaret Adduci, 79, passed away on October 23, 2026. Born January 5, 1947, Margaret will be remembered as a beloved and cherished presence—kind-hearted in spirit, generous in care for others, and brightened by a warm sense of humor that stayed with her through life’s many seasons.
Throughout her life, Margaret built a career in sales and always worked to support her family, meeting responsibilities with steady devotion and an openhanded willingness to do what was needed. Her love for those around her was evident not only in what she provided, but in the gracious way she carried herself—offering encouragement, laughter, and quiet strength.
Margaret’s adventurous heart found joy in travel. She especially loved visiting Hawaii, Mexico, Switzerland, Greece, Italy, and Spain—places that reflected her curiosity and her appreciation for beauty, culture, and new horizons.
A loyal and faithful Catholic, Margaret was a parishioner of St. Mary’s Catholic Church in Buffalo Grove. Her faith was a constant, shaping her days with reverence and guiding her with a gentle, enduring kindness.
Margaret was preceded in death by her husband, Joe Adduci, and her parents, Joseph Quinn and Edna Catherine Markley. She is survived by her children, Melissa Oleferchik (Mark) and Joseph Adduci (Cheryl); her sister, Elizabeth Quinn Worrell; and her granddaughter, Catherine Oleferchik
