Hannah Andrew was the daughter of Nathaniel Seymour Andrews and his first wife, Sarah Comstock. I believe that she was their only child. In 1796 in Stillwater, NY Nathaniel married his second wife, Abigail Rice (b. 12 October 1765). Nathaniel and Abigail had six children, Arba, Ira, Nelson, Nathaniel, jr., Sidney, and Anna.
