History Sheridan, once the second largest town in Hamilton County, lies on the south edge of land originally owned by George Boxley, a merchant and miller in Virginia who had fled from there ahead of bounty hunters because he was also an abolitionist suspected of fomenting a failed slave rebellion in 1815. Considerable recent development has greatly increased the population of this historic town. The Sheridan Downtown Commercial Historic District encompasses approximately four blocks along Main Street from the former Monon railroad right-of-way north to Veteran's Park and Pioneer Hill, the site of the George Boxley Cabin, listed in the National Register of Historic Places.

No documentation supports the popular contention that Egbert Higbee started the town in 1860. Higbee, born in Ohio and brought to Adams Township as a child, did, indeed, lay out a town he called Millwood on land adjacent to the district school (built 1851) on the state road. He had acquired his land in parcels and filed his town plat in April 1866. Only two-and-a-half blocks divided into twenty lots, it was oriented in an east–west direction along the south side of the Lafayette-Noblesville state road, which Higbee designated as Main Street (present day Second Street; his “West Street” became Main). Higbee immediately began to sell off lots to enterprising merchants and a few mill owners, and the little village got its start. Higbee himself built a mill and laid out additions to his original plat. Caswell Boxley, however, subdivided the south edge of his land, which adjoined Higbee's plat across the state road and he laid out his own plat of Millwood immediately north and extending west of Higbee's. The initial town orientation was succeeded by one that placed Main Street in a north–south direction. In a few years the hamlet of Millwood applied for a post
