Amos Noë Freeman, the first full-time called minister of the Abyssinian Meeting House from 1841 to 1852, also served as an instructor in the school maintained there for African Americans. He and Christiana Williams Freeman acted as conductors on the Underground Railroad, maintaining both their home and the Meeting House as safehouses for freedom seekers. After leaving Maine, Christiana Freeman became a director of the Colored Orphans Asylum in New York City, and during the Draft Riots of 1863 she was instrumental in saving many childrens' lives.
