Eileen worked for Willard Inc. as the HVAC services coordinator for many years. She lived a simple but full life, with a huge heart and deep compassion for others—whether providing meals for the elderly, donating food and clothing to homeless shelters, or buying gifts so the children in her church parish would have something to open on Christmas morning. She was always the first to lend a helping hand, whether for a home improvement project or when someone needed guidance and reassurance.
Eileen also had a huge passion for gardening. Neighbors often commented on how beautiful her home looked, though she remained very humble. But most of all, her children were her most prized possession.
She was predeceased by her sister Marion Wiegand and her brother Joseph Marshall, Jr.
She is survived by her beloved husband, Alfred P. Vaillancourt, Jr.; her daughters, Kim Vaillancourt and Patricia Vaillancourt Marchesani (husband Guy); her son, Matthew Vaillancourt (wife Doris); and her siblings Barbara VanHorn, Geraldine Marshall, Janet Matthews, Wayne Marshall, and Kathy LaStella.
