Harriet Ward Sanborn Grosvenor (1823-1863) was an American writer and poet.
[1][2] She was born in Hampton Falls, New Hampshire on January 22, 1823, the daughter of Thayer S. Sanborn (1797–1874) and Deborah Ward (1804–1850).
In 1843 married Edwin Prescott Grosvenor, M.D., of Newburyport, Massachusetts, where the couple resided after the wedding.
At the age of 24, she wrote My Sister Emily, published by the Massachusetts Sabbath School Society.
After her husband's death in December 1856, Harriet supported her family largely by writing, which was an unusual achievement for a woman at the time.
