After receiving her degree in elementary education, she taught in Milwaukee, Waukesha, Oconomowoc and Stone Bank. She taught hundreds of students how to read and write over her forty-year career.

She is survived by her husband and their three children, Bridget Ann (Timothy McNair) and grandson, Alistair Tru; Colleen Elizabeth (Paul Moran), granddaughter, Mary Kathleen and grandson, Patrick O’Neil, and Patrick Timothy O’Neil (Amy Venables), granddaughters, Cassidy Dell and Nora Mae. She was preceded in death by her parents; infant sister, Elizabeth Clare; brother, Terrence Patrick; brother-in-law, Patrick M. McElwee; sister-in-law, Jean A. O’Neil; and nephew, Jim O’Neil. Survived by her brothers, Fr. Lawrence D. Gillick, S.J. of Omaha, NE, Michael H. Gillick (Margaret) and Patrick J. Gillick (Veronique); sister, Ellen M.

(Lynelle Webb) O’Neil of Rochester, MN; along with many nieces, nephews, cousins and dear friends. Mary Ann was a lifelong Catholic and she lived her faith through a life of service to others. She taught in the CCD program and was a member of the first team of lay Eucharistic ministers at St Jerome’s Catholic Church. Her love of music and singing led her to be part of the Five O’Clock choir at St. Anthony Parish and she was an active volunteer with Lake Country Caring for years. She was proud of her Irish heritage and traveled to Ireland three times. Additionally, she traveled through Europe several times and loved spending time at the family home on White Sand Lake in Lac du Flambeau in Northern Wisconsin. More than anything she loved her family and enjoyed sharing her home and beautiful gardens with them. In her retirement, she devoted her time and energy to her grandchildren and helped them to become the prolific readers and thank you note writers that they are today. When she was born, she cried and her family rejoiced. When she died, her family cried and she rejoiced. The family will receive friends on Saturday, April 23, 2022 from 10 a.m.-12 p.m. at St. Teresa of Calcutta Catholic Church, W314 N7462 Hwy 83, North Lake, WI. followed by a Mass of Christian Burial at 12 p.m. A private committal ceremony will be held at St. Jerome Cemetery, Oconomowoc.
