Why the map and the ground disagree
GIS lines in Randolph County come from digitized deeds and old tax maps, and photo alignment alone can shift them. When money or a court is involved near Ellis Grove, rely on recorded documents and a boundary survey rather than the county layer.
How Randolph County deeds describe boundaries
Illinois uses the Public Land Survey System: land near Fort Gage is located by section, township and range, with parts like the NE 1/4 of the SW 1/4. For a platted lot in Ellis Grove, the description is typically a lot and block on a recorded plat, which a surveyor will want to see.
Towns and land across Randolph County
Chester is the county seat, and Red Bud, Sparta, Baldwin, and Coulterville are among the other towns on the county map. Unincorporated communities in Randolph County, including Blair, Bremen, and Dozaville, show up as small groups of parcels along the roads. Randolph County had an estimated 29,815 people in 2023 (Census Bureau), spread across about 575 square miles. The Randolph County map mixes subdivision lots near Chester with farm and wooded tracts farther out.
Deeds and plats behind the Randolph County map
For land near Ellis Grove, the deed itself lives in the county recording office, and the map is an index to it. A deed book and page or instrument number on the county record is the quickest route to request the document for a lot in Ellis Grove.
Finding corner pins and surveys
Survey markers on a Randolph County tract are frequently slightly below grade, but one pin does not prove where the line runs. Check whether a boundary survey of the piece of ground near Baldwin was recorded; the county's recording office may already hold a plat, and an attorney can advise if it escalates.
On the ground with the map
When you walk a line near Evansville, take the parcel ID, the legal description and a printout from the county map; it keeps a conversation with a neighbor concrete. Take photos of any pins or markers you track down near Ellis Grove and note where they sit relative to the county parcel outline.
