Obituary For Mary E. O'Reilly

Mary Esther (Fitzgerald) O'Reilly of Waltham, while surrounded by adoring family members, passed away peacefully after a courageous battle on Wednesday, March 15, 2023. Mary was 76 years of age.
Mary is survived by her beloved and devoted husband of over 31 years, James Anthony O’Reilly
of Newton. Mary also leaves behind her sons David Scott Perry and wife Joanne of
Marlborough, James Joseph Perry, and wife Donna of Holliston, Scott Fitzgerald Perry and
wife Heather of Waltham. Mary was also a wonderful and caring stepmother and dearly loved
her stepchildren, Kelly Ann (O’Reilly) O’Byrne and her husband Rod of Belmont, Kristen
(O’Reilly) Fitzgerald and her husband Gregg of Newton, and James Michael O’Reilly and his
wife Erin of Wellesley.
Mary was born on November 6, 1946, the fourth of six children born to John Allison Fitzgerald
and Ann Patricia (Scannell) Fitzgerald of Somerville, MA. She is survived by her older brother Walter Fitzgerald and wife Diane of Methuen, and younger sister Julie (Fitzgerald) Carr and her husband Mark of Salem. She is predeceased by her first love and husband, George J. Perry, her sisters, Nancy Driscoll, Kathy Goldy and Joan Demeo. She was truly loved by all of her family, as well as many adoring nieces, nephews, cousins, extended family and long-time friends.
She had many friends from her time spent at Waltham District Court. Mary supervised the civil
court and had many beloved colleagues.
Mary could be described as selfless and was always putting family and friends above even
herself. She took great pleasure in watching the many accomplishments of her grandchildren,
Cameron, Shane, Tyler, Kyle, Derek, Jack, Dylan, Laney, Ryan, Sean, Reilly, Julia, MacKenna and
Mary enjoyed travel, gorgeous weather and the charming landscape of her Bradenton, FL
home. Most of all, she valued family and friends and all of the small, beautiful moments life
had to offer, and, of course, watching her cherished Boston Bruins. She will be sorely missed by all.

    Mary was a true gem: beautiful, warm, kind, and funny. The BEST. She had a spirited way with words that always made you laugh. Her ready ear and caring heart always made you feel loved. She had a softness that belied her steadfastness and quiet strength, which carried her through of some of life's toughest challenges. Her dedication to family was unmatched, and she was truly a wonderful Mum. I am heartbroken at her loss and of these times now gone by. My deepest condolences to her devoted husband Jim; her beloved sons and my childhood friends David, Jimmy, and Scott, and all her loved ones. Wishing comfort to you during this very sad time. I will miss her and forever remember her with complete and utter fondness. May she rest in peace 💚

    Mary, you were my bestie. I'll always remember how our friendship was almost immediate from the time we met. For 36 years we enjoyed each other's company and always supporters each other.We laughed and cried through life's ups and downs but mostly laughed because we just got each other's silly humor. You'll always be in my heart my dear friend. I will miss you terribly. Rest In Peace and save me a seat up there. ❤️ Elaine B.
