We can see the Caroline County landscape in 1875, thanks to an Act of Congress.  The Librarian of Congress was directed to create a large, detailed map of the county, possibly in connection with the  1876 Centennial or the 1870 national census.  The map shows the owner’s name for each farm house.  And the locations of roads, grist mills, sawmills, stables, and churches across the entire county.

The web map here lets you compare the 1875 map with modern satellite imagery and street map, like this:

The 1875 map was not drawn from accurate land surveys, so it doesn’t align perfectly with “ground truth”.  But you can use the “Synchronize Scale & Location” buttons to move the three maps together or separately.  You can compare different parts of the old map to what we see in Caroline County today.
