Springfield is a common name and known, in part, for being a common place-name in the United States. A Springfield can be found in 34 different states—at least four in Wisconsin, and no fewer than nine Springfield Townships in Pennsylvania. On the other hand, database studies suggest that there are many more common place-names, including Fairview, Midway and Oak Grove; accounting for all the place-names in the United States is made difficult by database ambiguities, but the reality seems to be that the popularity of "Springfield" relative to other names is more legend than fact http://wordways.com/commonp.htm.
