Find Madison County Genealogy
Madison County genealogy records start in 1810 when the county was formed from Franklin County.

Birth and death registration began in 1867, but other record types reach further into the past. This guide covers the key offices, record dates, and research tools that will help you search for ancestors in Madison County, Ohio. The Probate Court and Recorder's office on North Main Street are the two main stops for most genealogy requests.
Madison County Overview
Madison County Genealogy Record Sources
The Madison County Courthouse is at 1 N. Main Street in London, OH 43140. The Madison County Probate Court maintains birth and death records from 1867 to 1908, marriage records from 1810, and probate files from the same year. The county was carved out of Franklin County on March 1, 1810. For any event before that date, you will need to check Franklin County records instead.
The Clerk of Courts holds divorce and civil court records from 1810. The Madison County Recorder keeps land records from 1810 as well. Deeds, mortgages, plats, and military discharges are all on file. Land records in Madison County are especially useful because the county was settled by farming families, and property transfers often show connections between extended family members who moved together.
Madison County is a smaller county, so the staff at the courthouse tend to be more accessible. Call ahead if you plan to visit in person.
Vital Records in Madison County
Birth and death records at the Madison County Probate Court cover 1867 through 1908. Before 1867, Ohio did not require counties to register births and deaths in a standard way.

After December 20, 1908, the Ohio Department of Health assumed control of vital statistics for the entire state.
Marriage records at the Probate Court go back to 1810. That gives you over 200 years of marriage data for Madison County. Under Ohio Revised Code Chapter 3705, all vital events must be registered with local authorities. Marriage records are public in Ohio, and you can request copies from the court. Death records from 1908 to 1953 are at the Ohio History Connection in Columbus.
Probate files include wills, estate inventories, guardianship records, and adoption papers. Most are open to the public, though adoption records have restricted access.

The London Public Library also keeps genealogy and local history materials. Public libraries are underrated for genealogy work. They often hold newspaper files, obituary clippings, and reference books that are not available anywhere else. If you are in London doing research, stop in and ask what they have for Madison County families.

Census records from 1820 onward cover Madison County, and the 1850 census is the first to list every household member by name. Tax duplicate records from the 1810s and 1820s list property owners and can help you trace when a family arrived. Madison County was farming country from the start, and many families stayed on the same land for generations.
