Population over time
2 figuresWinslow fell from 338 to 281 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

Full fifty years ago, Lyman Brewster, a wealthy landowner, who had emigrated from Vermont to Tennessee, where he acquired a competency, turned his face North, and halted not until he reached the settlement then making at Peru, on the Illinois River. How long he tarried here, is not of record ; but, in the spring of 1833, he continued his prospecting tour, finally reaching the present site of Winslow, in Winslow Township, where he entered a claim, erected a comfortable house, cleared 80 acres of ground, and established " Brewster's Ferry," the first ferry in the county, and for many years the only one accessible to emigrants in crossing the Pecatonica River. Mr. Brewster was the first white man who ever made a claim in Winslow Township, and after a brief stay, by which time others had followed in his venturesome footsteps, he rented the ferry and adjoining property to William Robey, and returned to Peru, where he died.

Among those who made their adventurous way into the township the same year that witnessed the advent of Mr. Brewster, were' Joe Abenos and A. C. Ransom, the latter going back East for his family, after surveying the outlook, and returning the following spring. Abenos assisted Mr. Brewster in the management of the ferry, while Ransom settled in Section 36, a mile and a half southeast of the village of Winslow, where he entered a claim and laid off the town of Ransomburg. But the town did not prosper as was anticipated, Winslow appropriating the new-comers because of its more favorable site, and Ransomburg in time was utilized for farming purposes, Robert Pilson now residing and farming within its original metes and bounds.

The advance thus made by the brave pioneers, and the struggle they encountered in contending for the permanent establishment of the cause of civilization in this uninhabited wilderness, was not without results in paving the way for the rise and progress of this portion of the county through the influence of the immigration that succeeded their coming.
