Obituary, Hampshire Gazette and Northampton Courier, 14 June 1870:
Miss Sophia Smith died on Sunday, at the advanced age of 74 years. She was well known in all this section as a lady of great wealth, of benevolent disposition and blameless and irreproachable life. She was the sister of Austin Smith, and received from him and a sister, property to the amount of $200,000. In addition, she had some $30,000 from the estate of her father. A few years since she gave $30,000 to Andover Theological Seminary, and she also gave liberally toward founding a public library in the town of Hatfield. Her private charities were numerous and her memory will be cherished with affection by a large circle who have been recipients of her benefactions.
Subsequent reports of the inventory of her estate, however, revealed that it was larger than originally estimated.
