I was very happy to finally visit this historic New England house. After several years of renovation work done on it, it re-opened to visitors in 2022. Finally, on September 17, 2023, I went. There was a nice group of about 10.

From the webpage of HistoricNewEngland.org is this description, "Built between 1694 and 1701 for a farming family, Browne House contains rare surviving architectural features from the late 1600s. In a near ruinous state when it was acquired by Historic New England founder William Sumner Appleton in 1919, the house was painstakingly restored in what is acknowledged to be the first fully documented restoration in America. See how a late 1600s family lived in what was considered a “mansion house” at the time." "There is one large room on the first floor, which incorporated living, cooking, and sleeping space. The upper chamber contains an extremely rare three-part casement window frame."
I love the virtual tour of this house at https://my.matterport.com/show/?m=o5zZ9ogUVQX You'll be able to see both floors, so now I know what was on the second floor.
