From the History of Easton, Mass., by W. L. Chaffin, 1886, p. 50:
"Josiah Keith was a son of the Rev. James Keith, of Bridgewater. In 1717 he bought over two hundred acres of land on the easterly side of Mulberry-Meadow Brook, afterwards called Leach's Stream, and became a resident here either that year or the next... His house was probably built in 1717, and is the oldest house standing in town. An addition was made to it at a later date. The old part of it is the west end, at the left of the accompanying picture as seen by the observer. This remains about as it was, and is an interesting relic of the olden time. It was used for an inn as early as 1724, Josiah Keith then being a licensed innkeeper."
The house is still standing today, on Bay Road.
