Nancy Baillargeon (Mihouski), of Westfield, Massachusetts, passed away peacefully at home on June 19, 2026, at the age of 86. Nancy was the beloved wife of William Baillargeon, the love of her life. Together they shared a beautiful marriage and celebrated their 64th wedding anniversary in March. A devoted wife, mother, and grandmother, Nancy found great joy in creating a warm and welcoming home for her family. She especially loved decorating for the holidays, with Christmas being her favorite season. Her treasured Annalee dolls and decorations filled her home with charm and holiday spirit, making it feel like something out of a Hallmark movie. Nancy also enjoyed spending time at the beach, reading, and watching classic Westerns on television. She was affectionately known as "Nan," "Gram," and "Mimi" by those who loved her most. In addition to her husband William, Nancy is survived by her four children: William Baillargeon Jr. and his wife Paula; Debra Jez and her husband David; Brian Baillargeon and his wife Jessica; and Glen Baillargeon and his wife Renee. She is also survived by her five cherished grandchildren: Sheila, Samantha, Jenny, Rachel, and Tanner. Nancy's love, kindness, and dedication to her family will be deeply missed and forever remembered. A private family burial will be held at a later date.
