Gorham was born in either Maryland or Virginia,[2] but her life is not documented until 1880, when she visited family members who had moved to Liberia, presumably via the American Colonization Society.
After this visit, she returned to the United States and was involved at the Charles Street African Methodist Episcopal Church.
In 1888, at the age of 56, she joined AME missionary John Frederick in Sierra Leone,[3] travelling to the Magbelle mission in Sierra Leone (about 75 miles from Freetown), as the AME's first woman foreign missionary.
At Magbele she established the Sarah Gorham Mission School, which gave both religious and industrial training.
