Logan County Overview
Logan County Genealogy Record Sources
Logan County was formed from Champaign County on March 1, 1818. The courthouse in Bellefontaine is the hub for genealogy research. The Logan County Probate Court maintains birth and death records from 1867 through 1908, marriage records from 1818, and probate files from the same year. If you are looking for a marriage record from the early 1800s, the Probate Court is where you start. Staff can help you pull the right volumes and find the entry you need.
The Logan County Recorder holds land records dating back to 1818. Deeds, mortgages, plats, and other property documents are all filed here. Land records are some of the most useful genealogy tools because they show where an ancestor lived, when they bought or sold property, and sometimes who their neighbors were. The Recorder's office can help you search by name or parcel number.
Court records in Logan County also go back to 1818. The Clerk of Courts keeps civil and criminal case files, including divorce records. These files are public under Ohio law.
Vital Records for Logan County
Birth and death records at the Logan County Probate Court cover the years 1867 to 1908. These early vital records were kept in ledger books with brief entries. After December 20, 1908, the state took over. The Ohio Department of Health now holds birth records from that date forward. Death records from 1908 to 1953 sit with the Ohio History Connection in Columbus. Death records after 1953 are at the state health department.
Marriage records at the Probate Court date back to 1818. That gives you over 200 years of marriage files to work with. Under Ohio Revised Code Chapter 3705, vital events must be registered with local authorities. Marriage licenses and returns are public records in Ohio, so you can request copies from the court without special permission.
Probate files from 1818 include wills, estate inventories, and guardianship records. These can reveal family connections that vital records alone might miss.
Note: For Logan County birth records after 1908, contact the Ohio Department of Health at 614-466-2531 to order certified copies.

The Campbell Library in Bellefontaine also has genealogy and local history materials. Public libraries are often overlooked for genealogy work, but they can hold newspaper clippings, obituary files, and city directories that fill in gaps between official records.
