Anna was the daughter of Henry Warner, a wealthy New York City lawyer.
When he lost most of his fortune in the 1837 depression, the family was forced to move to their summer home (Good Craig) on Constitution Island in the Hudson River. It was then that Anna and her sister Susan began writing to earn money.
They also conducted Bible classes for cadets at the nearby Military Academy at West Point, where their uncle had been a chaplain, 1828–38. In memory of her, the Academy’s Constitution Island Association manages the Warner’s island property as an historic site.
