The Morrill Brothers essentially ran the Boston Jewelers' Club for many years and were extremely influencial in the Boston jewelry trade.

The older Morrill Bros. & Co. firm reorganized as Morrill Bros. Co. in September 1893 with a capital stock of $100,000. The officers were named as Charles F. Morrill, President; Alvin T. Morrill, Treasurer; and Oakes A. Drinkwater, Secretary.

The April 25, 1894 issue of The Jewelers' Circular reported, "It is rumored that C.F. Morrill, of Morrill Bros. & Co., Boston, will purchase the plant of the Seery Mfg. Co., of this city, who failed some weeks ago." In 1895, reports claim this factory was sold by Morrill to Esset & Barry.

In 1896, Charles F. Morrill withdrew from the company to focus on real estate developments (The Jewelers' Building of Boston), and the company was reorganized as Morrill Bros. Co.

The company became bankrupt in 1898 after an unsuccessfull attempt to move into the trending bicylce market. However, it was able to continue after a settlement with creditors. The following year, the company was assigned to Alvin T. Morrill. This company was then rolled into the newly-formed firm of Morrill, Clough & Thayer.
