The building at 9 Tryon Street in South Glastonbury may have been built as early as 1720. Around that time Thomas Hollister and Thomas Welles started a saw mill on the east side of nearby Roaring Brook. The mill was linked to the shipbuilding industry in the area at the time. By the mid-eighteenth century this early operation had developed into what was known as the “Great Grist mill at Nayaug.” The house at 9 Tryon Street may have been the bake house associated with that mill that is mentioned in a 1783 deed. According to one source, the Welles-Hollister grist mill and bake oven on Roaring Brook at Nayaug was completely destroyed in the great flood of 1869 and the mill had to be rebuilt on the northwest side of the bridge over Roaring Brook at the foot of High Street. Later, in the early twentieth century, there was a feldspar mill on the east side of the brook and the building at 9 Tryon Street may have served as the mill office of owner Louis W. Howe and then as housing for a spar mill worker’s family. Howe sold the house c. 1928 to Mrs. Aaron Kinne, who had the interior remodeled c. 1940 to designs by restoration architect Norris F. Prentice. It was remodeled a second time in 2002.
