Search Putnam County Genealogy
Putnam County genealogy records start in 1834 when the county became fully organized in northwest Ohio. The county seat is Ottawa, and the courthouse at 245 E. Main Street is where most records live. Putnam County was formed from Shelby County back in 1820 but took years to get enough settlers for a working government. If you are tracing family lines in this part of Ohio, the Probate Court, Clerk of Courts, and County Recorder each hold different sets of genealogy files. This page covers the key sources and how to get to them.
Putnam County Overview
Putnam County Probate Court
The Putnam County Probate Court at 245 E. Main Street in Ottawa, OH 45875 is the first place to look for genealogy records. The court holds birth and death records from 1867 to 1908. Marriage records go back to 1834. Probate records start from 1834 as well. Those marriage books cover nearly 200 years of Putnam County families.
Probate files here include wills, estate inventories, guardianship papers, and adoption records. Wills are among the most useful genealogy documents. They name heirs, describe property, and sometimes reveal family relationships that are not in any other record. Estate inventories list everything a person owned at death. Guardianship papers show who took care of minor children. All of these are public except adoption files, which are restricted under Ohio Revised Code Section 3705.126.
Vital Records in Putnam County
Ohio counties kept birth and death records until December 20, 1908. After that date, the state took over. For Putnam County births and deaths after 1908, contact the Ohio Department of Health Bureau of Vital Statistics. They handle all certificates from that point forward. You can order online or by mail.
Death records from 1908 to 1953 are at the Ohio History Connection in Columbus. For records before 1867, there are no civil registrations. The state simply did not track births and deaths at the county level before that year. Church records, family bibles, and cemetery inscriptions are your best bet for that era. Putnam County has a strong Catholic heritage, so parish records may be especially rich. Under ORC Chapter 3705, all vital records must follow state filing rules. Section 3705.09 requires birth certificates within ten days of birth.
As of January 2025, the state charges $21.50 per vital record search through the Ohio Department of Health per ORC 3705.24. That fee applies whether a record is found or not. County offices set their own copy fees for marriage records and probate documents. Online orders take about three weeks for delivery. Mail orders to the state can take four to six weeks. If you need a certificate fast, the state office in Columbus is open for in-person requests on weekdays from 10:00 AM to 2:00 PM.
Land Records and Court Files
The Putnam County Recorder keeps land records from 1834. Deeds, mortgages, plat maps, and military discharge papers are all filed at the office in Ottawa. Northwest Ohio was part of the Great Black Swamp, and much of Putnam County was not settled until the swamp was drained in the mid-1800s. Land records here tell the story of that transformation from wetlands to farmland.
The Clerk of Courts handles divorce records and civil case files from 1834. Divorce records can be rich sources for genealogy, listing names, ages, dates of marriage, and children. Ohio is a public records state, and most court files are open to anyone under Title 37 of the Ohio Revised Code. Visit the courthouse in Ottawa for copies. Older records from the 1800s may take extra time to pull.
