Mary A.F. Emerson (1831-1913) was born in Ipswich, Massachusetts, and lived in many places throughout the state, including Boston, Waltham, and Cambridge. She was married to Elijah Emerson (1820-1904), a violin maker who for many years located his business on Court and Hanover streets in Boston. Although she was familiar with and studied the works of Mary Baker Eddy, there is no record of her studying with Eddy or joining the Christian Scientist Association or Church.
