Find Putnam County Genealogy

Putnam County genealogy records are held by the county clerk in Hennepin, a village in north-central Illinois along the Illinois River. The clerk keeps birth, death, marriage, and land files for the county. Putnam County is the smallest county in Illinois by land area, covering just about 160 square miles. With roughly 5,000 residents, it is also one of the least populated. You can search Putnam County genealogy records by visiting the courthouse, calling (815) 925-7129, or mailing a written request. The IRAD depository at Northern Illinois University in DeKalb stores older Putnam County government records that have left the Hennepin courthouse.

Putnam County Clerk Records

The Putnam County Clerk is at 120 N. 4th St, Hennepin, IL 61327. The phone number is (815) 925-7129. This office holds vital records, marriage licenses, and land documents for Putnam County. Birth and death records start around 1877. Marriage records may go back to 1825 when the county was organized. The Counties Code (55 ILCS 5) makes the county clerk the legal custodian of these files.

Hennepin is a very small community and the clerk's office handles a minimal volume of requests. That is an advantage for researchers. You are unlikely to wait long for help. Staff are familiar with the local collections. Walk-in visits get the quickest results. Bring the full name and any dates you have for the person you need. Because the county is so small, the total volume of records is more manageable than in the larger counties, and specific entries can often be found faster.

Mail requests work well for out-of-state researchers. Send a letter to the clerk with the full name, dates, record type, your payment, and a photo ID copy. Make checks payable to the Putnam County Clerk. Put your phone number on the letter.

Putnam County Land and Early Files

Putnam County's small size has a direct impact on genealogy research. With only 160 square miles, the county has always had a small population. Fewer people means fewer records, but the records that exist can be easier to search because the indexes are thin. Land records from the 1820s through the 1870s are the main county-level source for the period before vital records started. Deeds, mortgages, and property transfers can show when a family lived in the Hennepin area and what land they owned along the Illinois River.

The recorder's office in Hennepin holds all property files. The Local Records Act (50 ILCS 205) requires that these documents be preserved. The Illinois State Archives also keeps public domain land sale records from original federal purchases. Those are free to search online. For a county this small, the Archives land records can cover a large share of the early property transactions.

Note: Putnam County's original boundaries were larger than today; some early records may cover areas now in other counties.

Putnam County Records at IRAD

The IRAD depository for Putnam County is at Northern Illinois University in DeKalb. Call (815) 753-1807 to check what Putnam County files they have. IRAD stores older government records that have been transferred from the Hennepin courthouse. This can include court case files, probate records, naturalization papers, and historical vital records. Research is free and you can photograph documents at no charge.

Staff take mail and phone requests but limit each to two names. For more detailed research, visit the DeKalb campus in person. Use the IRAD holdings database to search what Putnam County records are at NIU before making the drive. DeKalb is about 70 miles northeast of Hennepin. Because Putnam County is so small, the total volume of records at IRAD is likely modest compared to larger counties, but those records may be quite old given the 1825 founding date.

The Vital Records Act (410 ILCS 535) sets these access rules.

For a small county like Putnam, these statewide indexes may capture a good portion of the total records. The Freedom of Information Act (5 ILCS 140) governs public records broadly in Illinois, but vital records have separate rules under the Vital Records Act.
