This is the United States Geological Survey of 1893, which notes that it was surveyed 1889-1890. The scale is 1:62500; that doesn't mean a lot for a map with zoom, but it shows the level of detail you might expect. The counter lines are each 20 feet.
In the Roton Hill area, this map shows practically every home, although the separate homes along Flax Hill are shown aren't differentiated.
