Henry County at a glance: towns and land
Start your bearings with Cambridge, the county seat, then Colona, Galva, Geneseo, and Kewanee. The county was organized in 1825 and named for Patrick Henry, so some tracts carry a long chain of deeds. Census Bureau estimates show 48,448 residents in 2023 and around 823 square miles of land in the county. That density means a real mix on the map: platted neighborhoods near Annawan, and larger tracts on the rural roads.

How accurate are Henry County, IL property lines?
A lot line on the Henry County plat map near Annawan is a drawing based on deeds, not a measurement taken on site. Legal descriptions in Illinois usually lean on the section grid, so learning to read 'NE 1/4 of Section 12' pays off quickly around Annawan. A survey is the only document that settles where a Henry County boundary actually runs.
A note on timing and acreage
A lot in Atkinson that sold last month may still show the previous owner on the map. For a rural tract near Nekoma, get acreage from a survey, not the tax record, if it matters for a deal.
