Houses at 24 and 26 Guerny Street in Cape May, New Jersey.  Part of the Cape May Historic District.  12-30 (evens) Guerny Street are known as "Stockton Place", were identical houses designed by architect Stephen Decatur Button.  12 and 14 Guerny seem to have disappeared (or perhaps were typos) but the other houses remain.
