Population over time

2 figures

Henderson grew from 255 to 266 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.

History of Knox County, Illinois, published 1878 names this settlement in its chapter on Henderson Township. These are the passages that mention it, exactly as the scans read.

This township was the first in the county to have the home of a white man located within its boundaries. Here, in February of 1828, Daniel and Alexander Robertson settled. Many of the first incidences of the county occurred in this township, and, as a greater portion of the first chapter of this wrork is located here, and many other historical items given all through the book, we refrain from repeating. Here, on sections 23 and 26, the Indians had their corn-fields and cultivated the soil for years.

In an early day, on section 30, near the creek, a well was dug. On arriving at a depth of 60 feet the workmen came to what seemed to be an Indian camping-ground. Ashes, stumps, and general rubbish were there as fresh as though the fires had just gone out. A red cedar log was tJso found.

H. M. Sisson, of this township, has done much to better the class of stock, and deserves credit not only from the citizens of the township, but of the county. He has, perhaps, the oldest horse in the county. It has been in his family for thirty- six years, and he has plowed with it each year for thirty years.
