Mary Jane Mosier (née Rooney), 84, of Harrington Park, NJ, passed away on Sunday, October 11, 2026.
Mary Jane was the beloved wife of Edson and a devoted and loving mother to Lisa; Kenneth and his wife, Ly-Cheng; Sarah Knigin and her husband, Michael; and Jimmy and his wife, Kate. She was a proud and adoring Nana to her ten grandchildren: Nicole, Justin, Kelsey, Jasmine, Abigail, Edson, James, Zachary, Olivia, and Jack, who brought her endless happiness and joy. She was also a loving aunt and cousin to many, cherishing the special bonds she shared with her extended family and always making everyone feel loved and valued.
Mary Jane lived a life defined by her generosity, strong faith, and unwavering devotion to her family. She gave freely of her time and talents, always putting the needs of others before her own. She worked tirelessly to provide for her family and believed that time spent together was life’s greatest gift. Some of her happiest moments were spent enjoying summer beach vacations in Avalon and Stone Harbor, surrounded by the children and grandchildren she loved so dearly. No matter how busy life became, her family was always her first priority.
Her caring nature extended far beyond her family. For more than 30 years, Mary Jane served as the school nurse for Northvale Public Schools, where she dedicated herself to the health and well-being of generations of students. She was also an active member of the Harrington Park Board of Education and Emergency Medical Services, a past president of the New Jersey Education Association, and a longtime lector at Our Lady of Victories Church.
A woman of deep and abiding faith, Mary Jane believed wholeheartedly in the power of prayer. Her faith guided her throughout her life and was reflected in the kindness, compassion, and generosity she shared with those around her.
Above all, Mary Jane will be remembered for her selfless love, her devotion to family, and the countless ways she made life better for others. Her greatest legacy is not only the many lives she touched, but the close and loving family she worked so hard to bring together.
She was predeceased by her parents, Lawrence and Mary Rooney, and her beloved sister, Nancy Duffus, with whom we can only imagine she is joyfully reunited, singing and dancing together once again to “Sisters” by Rosemary Clooney.
“May the road rise up to meet you. May the wind be always at your back. May the sun shine warm upon your face, the rains fall soft upon your fields, and until we meet again, may God hold you in the palm of His hand.”
Family and friends are invited to celebrate Mary Jane’s life on Friday, October 16, 2026, from 3:00 to 7:00 PM at Pizzi Funeral Home, 120 Paris Avenue, Northvale, NJ. A funeral service will be held at 6:30 PM.
