After a brief time operating under the name Thomas Griswold & Co. during the Civil War, A. B. Griswold & Co. became the successor to Hyde & Goodrich in 1865, carrying on the business at the same location. The firm continued the practices of its predecessor: hiring local craftsmen to make custom goods while also contracting with major manufacturers to sell mass-produced silver flatware and hollowware. The company was one of the largest agents for the Gorham Manufacturing Co. of Providence, Rhode Island, and Wood & Hughes of New York and carried many of their patented silver patterns.
