The Early Years. Ellen, with her twin sister Elizabeth, was born November 26, 1827, to Robert and Eunice Harmon. With eight children in the family, home was an interesting and busy place. The family lived on a small farm near the village of Gorham, Maine, in the northeastern part of the United States. However, a few years after the birth of the twins, Robert Harmon gave up farming, and, with his family, moved into the city of Portland, about twelve miles east.
