Because I have Fifield ancestors, a kind family researcher sent me a portrait photo of Charles B. Fifield, MIT Class of 1879, thinking that he might be in my Fifield ancestor chain.No direct relation that I can discern and a brief search in the 1880 US Census finds a Charles B., b. abt. 1860 in MA, living with his father Charles H. Fifield (b. abt. 1829 in NH) and mother Caroline A. (b. abt. 1833 in ME), all living in Salem, MA.Don't know wheteher this is the correct Charles B.
If you are of the family of Charles B. Fifield, MIT Class of 1879, I would be happy to e-mail this portrait to you.
