Considering that Petworth is currently a neighborhood densely populated by Wardman rowhouses, imagining it as a sprawling takes a little bit of imaginative juices. If you happen to be short on aforementioned imaginative juices, this map from 1859 should do the trick. Surveyor Albert Boschke published topographical maps of D.C. in 1859 after having surveyed it throughout the latter part of the decade. Perhaps the most interesting part of this work isn't seeing the prevalence of trees (because Petworth is still pretty green) or the lack of streets, but seeing the names of the landowners dotted throughout the spread. Today, that information would cover up the entirety of the map.
