HistoryA character grade: shown, never part of Sumpter’s overall grade.
Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Sumpter’s 0.0 sits below most of its state (28% of Wisconsin towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

Herman E. Stone grew up on the old farm established by his father in the town of Sumpter, attended the schools maintained in that community, and then applied his best energies to making a home for himself, and he continued to be identified with farming there until six years ago, when he retired to a comfortable home in the City of Baraboo.
