Jeanne Eileen Trionfero, 75, passed away peacefully surrounded by loved ones after a fierce battle with brain cancer on Thursday September 3, 2026.
A lifelong resident of Oswego, Jeanne was the daughter of the late Santo and Catherine “Emma” Grasso. She graduated from St. Paul’s Academy, Oswego Catholic High School and SUNY Oswego, taking great pride in being an alumna of each. An educator who loved lifting up children much of her life, beginning her career at Oswego County BOCES and retiring from Oswego High School, she worked at Grant’s, JC Penney and Valti Graphics through the years as well. Jeanne married Marshall Trionfero in August of 1973, many years after first meeting him in kindergarten, and they started their family (and 50+ year marriage!) First came Mara, then Michele, then Marcello, who each exude Jeanne’s essence and spirit in their own unique ways. An avid reader, Jeanne also enjoyed traveling on adventures great and small with her family, friends, and the Granby Seniors. Each Christmas, her many varieties of festive Italian cookies were enjoyed by family, friends, colleagues, neighbors and anyone who seemed like they might need a little cookie to cheer them up. In all spheres of her life, she enthusiastically showed kindness and compassion, with a signature side of sass.
She is survived by her husband, Marshall, their three children, Mara (Jamie) Trionfero Lucas of South Bend, IN, Michele (Jason) Meltzer of Rocky Hill, CT and Marcello (Marie) Trionfero of Oswego; her sister Margaret (Gary) Bower and brother Philip (Toni) Grasso; brothers in law Joseph (Denise) Trionfero, Kenneth (Debbie) Trionfero, sister in law Rosanne (Fred) Maxon, grandson Jackson Lucas, several nieces, nephews, cousins and friends too numerous to list.
She was preceded in death by her parents, and her brother, Robert Grasso. The family would especially like to thank Jeanne’s caregivers both at Upstate Cancer Center and Morningstar Residential Care Center. Funeral services will be 11:00 AM Wednesday at Christ the Good Shepherd Church where a Mass of Christian Burial will be celebrated.
Burial will in St. Peter’s Cemetery.
Calling hours will conducted from 4:00 to 6:00 PM Tuesday at Sugar & Scanlon Funeral Home, 147 W. 4th. St Oswego.
In lieu of flowers, the family encourages honoring Jeanne through donations to the Oswego Chapter of Blessings in a Backpack.

Kenn and Terri Kern
Marshall, My deepest and most sincere condolences for the loss of your sweet Jeanne. She was the sweetest with the kindest heart.
Hugs and prayers you and you beautiful family. Martha
The Trionfero family will always have a place in our hearts as our best “old neighbors” from when we bought our 1st house. Jeanne taught me how to be attentive but not over-bearing in my role as a mom to kids living in the city. She and Marshall were the best front porch neighbors and we valued their friendship.
Marshall, Marc, Mara, and Michele, Jeanne does live on in all of you. May she rest in peace having lived a good life. We are so sorry for your loss.
Cathy & Doc Nelson, Trav & Kayla too.
Rest in peace Jeanne, secure in the knowledge you have left a wonderful legacy behind. You will be sorely missed by family and friends.
Love,
Margie
PS: As it happens, It was not such a fine kettle of fish after all. So very sorry.
