1907: An exhibit featuring almost 500 historical objects, contributed by residents pertaining to the town, is presented for New Milford's bicentennial at New Milford Public Library's Memorial Hall. Many people express regret the exhibit is not displayed longer and suggest a permanent place for the objects would someday be made available.

1915: A group of prominent citizens, many of whom had been involved with the town's bicentennial exhibit, establish an historical society and museum.

March 19, 1915: New Milford Historical Society is incorporated. William G. Green, Frank W. March, Charles M. Beach, Ina J. Beach, Helen M. Boardman, Kate T. Boardman, Dr. George H. Wright, Ella C. Wright, Flora G. Stilson, Joseph H. Nettleton, Charlotte E. Roberts, Henry S. Mygatt, Nancy F. Mygatt, Robert E. Murphy, Sarah J. Roberts and John Pettibone are named as the people who make up the New Milford Historical Society "for the purpose of promoting historical and genealogical research, particularly in regard to the town of New Milford and its inhabitants, and collecting and preserving antiquarian and historical objects and records," according to a copy of House Bill No. III.

1915-64: The museum is housed in the home of Kate and Helen Boardman at 55 Main St., the site where is currently the Bank of America. Helen dies shortly after the museum is incorporated, and Kate operates it until 1922.

1956: The Knapp House -- once the home to cobbler Levi S. Knapp -- is donated to the historical society by Mary Clissold Knapp, the last member of the family to own the property. She and her sister, Margaret, had lived in the house for many summers, but spent their winters in Hartford with their brother, Admiral Harry Knapp. The bell from Admiral Knapp's flagship, the U.S.S. Pittsburgh, graces the Village Green. The house dates back to the 1770s, while later additions and renovations date to 1815.

Elijah Boardman, who resided in the Elijah Boardman House, which is occupied today by the Cramer & Anderson law firm.

The door of the former United States Hotel (circa 1790)-- located at the corner of Main and Bank streets, now the site for Robertson Jewelers -- is installed at the museum.
