This property map of Columbia Heights from 1869 shows John Sherman’s subdivision with the old street names (learn about the street names here). Make sure you click on it for more details because it’s very interesting. For some reference, Kennesaw Ave. is now Irving St., which runs right by DC USA (aka, Best Buy and Target) today. Obviously none of those plots are single family homes today. The road from Pierce’s Mill is today’s Park Rd.
