This is a great set of Naps. They are some of the earliest topographic maps of New Jersey. They won't tell you where your ancestor's farm was, but they do deliver a good sense of of the pre-development "lay of the land" and a lot of other information about the state. The files are large and so far have required 60-90 seconds to load over broadband.
