Rev. David Smith built a small post office building around 1852 which he operated next to his home on Maple Avenue in Durham. When he died in 1854, he was succeeded by his daughter, Catherine. When she married Henry L. Ellsworth in 1857, the building was moved to its current location on Main Street, across from the town green. In the later nineteenth and early twentieth centuries, the old post office housed a succession of stores, eventually becoming a residence. The building has been altered, with an addition on the east end, facing away from the street.
