Antoinetti Marie "Del" Shanahan Obituary
Age 78, of Upper St. Clair, peacefully passed away on Tuesday, December 30, 2025, at home with her husband by her side. She was the beloved wife of James F. Shanahan for 56 beautiful years; loving mother of Michael (Kristie) Shanahan, James (Jonette) Shanahan, Jeffrey (Tara) Shanahan, Patrick (Christina) Shanahan, and the late Brian (Karen) Shanahan; and a treasured grandmother, lovingly known as “Nona,” to Brynn (Colton) Cyphert, Sutton, Ryan, Colin, Nolan, Gabriella, Marin, Nick, Quinn, Mae, Patrick, Evelyn, and Amelia Shanahan. A devoted and hands-on grandmother, she was deeply involved in her grandchildren’s lives and took immense joy in every milestone, big or small. She was a proud great grandmother to Eloise Cyphert. She was the caring sister of Carolyn (Late Bernie) Keneavy and Tony (Shannon) Delewese, and the daughter of the late Tony and Wanda Delewese.
Antoinetti leaves behind a remarkable legacy of love, strength, and devotion. Affectionately known as the “Sheriff,” she raised five boys with confidence, humor, and an unmatched determination, always ready to take on any challenge. She was the glue that held her family together, making sure everyone was cared for, supported, and kept on track. Her family and friends were always her greatest priority, and she dedicated her life to nurturing them with fierce love and steady guidance.
As someone who always wanted to get people together, Antoinetti was known for her exceptional ability to plan and bring people together no matter what the occasion. From holidays and birthdays to everyday moments, she was the heart behind every gathering, ensuring that no detail was overlooked and that each occasion was filled with warmth, laughter, and joy.
In the face of adversity, Antoinetti demonstrated extraordinary courage and resolve. Following her cancer diagnosis, she set a clear and heartfelt goal: to live long enough to witness her first great grandchild, Eloise who was born in August. With grit, grace, and determination, she achieved that, a testament to her resilience and strength. Her legacy will live on through the traditions she created, the memories she cherished, and the enduring love she gave so freely to all who were blessed to know her.

Jim, I'm so sorry for your loss. She was such a blessing to you and your family. What a great gal to leave such a collection of wonderful memories. As I close in on 56 years with my Joanna I can only imagine your feeling of loss. I'll leave with this thought expressed by an old farmer I used to buy hay from. If I don't see you again on this side, I'll see you on the other side. I wish you all peace.

Jim, I was moved by this news and am praying for you and your family. And I had to take a moment to reflect on why Antoinette's passing made such an impact on me. We were not in the same circles, yet she always took time to pause momentarily, engage me in a quiet, friendly, respectful moment and leave me feeling somehow MORE before she moved on to her next encounter. I get the sense that never changed. That that is who she is and that she continues to check on all of us, but especially you and your family. A marvelous human with the gift of diplomacy that most of us try to cultivate in our lives, yet for her it was always the automatic moment in time that left others feeling they were special. Prayers, brother.
