The town of Delavan is one of the original towns into which the county was divided by act of the Territorial Legislature of January 2, 1838. By that act, it received its name, and, as then defined, embraced the southwestern quarter of the county, and comprised what are now the towns of Darieu, Sharon, Walworth and the present town. The original town was divided by setting of Towns No. 1, in Ranges 15 and IB east, in 1839, to which was given the name of Walworth. Subsequently, January B, 1840, Darien, lying immediately west of the present town, being Town No. 2, in Range 15 east, was set off, leaving the limits of Delavan as they now are, with the exception of a single section. No. 1, which was set off February 2, 1846, to help form the present town of Elkhorn. It was named Delavan in honor of E. C. Delavan, a prominent temperance advocate of Albany, N. Y.

The sm-face of the town is generally quite rolling, but a very small portion being flat and level. There is considerable marsh land, the greater portion of it lying in the vicinity of Delavan Lake. These marshes now constitute great natural hay meadows. Around Delavan Lake was originally a large amount of timber, mainly oak, with some hickory and a little red cedar and poplar. Extending nearly across the town, from the village of Delavan to Elkhorn, is a level tract of land known as Delavan Prairie, while in the western part is Blooming Prairie, which is smaller and of less importance.
