Harriet Osborne, Baroness Godolphin was a British noblewoman. An illegitimate child, her mother was the society figure Henrietta Ponsonby, Countess of Bessborough, who became pregnant by her longtime lover Lord Granville Leveson-Gower. Henrietta gave birth to the girl in secret and sent her to be raised by a foster mother, though she stayed in contact through letters and gifts.
