Elizabeth Collins Stoddard was the matriarch of the aristocratic Collins family of Collinsport, Maine. Although a woman of great pragmatism, she was passionately devoted to her family. She was a leading force in the family business, but conducted most of her day-to-day affairs from her home at Collinwood. Elizabeth shared the ancestral home with her brother, Roger, his young son, David, and daughter Carolyn. She employed her niece Daphne to work as the family accountant.
