Piatt County Early Records
Piatt County was formed in 1841 from portions of DeWitt County and Macon County. That formation date matters for genealogy. If your ancestor lived in the Monticello area before 1841, their records would have been filed in either DeWitt or Macon County. Marriage licenses, land deeds, court files, and any other county records from before 1841 are in those parent counties. Researchers tracing early settlers in this part of central Illinois need to search all three counties to get a complete picture.
After 1841, Piatt County began keeping its own records. Land files from the early years of the county can place a family in a specific area and time. Deeds and mortgages are held by the recorder's office in Monticello. The Local Records Act (50 ILCS 205) protects these documents from being discarded. The Illinois State Archives has public domain land sale records from the original federal purchases that are free to search online.
Note: For Piatt County families before 1841, check DeWitt County and Macon County records first.
