Land and Property

Land records are extraordinarily accessible in McHenry County. The County Recorder's web site includes a free web search. The index to deeds, mortgages, affidavits, liens, and more can be searched by name and/or document type and/or date. The system can return a maximum of 200 hits, and begins with the most recent transactions first. Because the index contains thousands of entries, searchers may need to include a date range as well as surname, to ensure that the oldest records are included in the results.

Records from the original leather-bound first volume of the McHenry County Commissioners’ Court Minutesfrom 1837 - 1848 are available in PDF format online at the County Recorder's site, as well. This Board established precincts (townships would come later), set the rate for taxable property, and began the process of laying out roads and determining the location for the county seat. Because Lake County wasn't divided off until March of 1839, early Lake County information is included.
