Main Street holds the main record collections for the area. Researchers can dig into birth, death, marriage, probate, court, and land records through several county offices. Preble County borders Indiana, and many families in this area crossed back and forth between the two states. This guide walks through the key record sources for your Preble County genealogy search.
Preble County Overview
Preble County Probate Court Records
The Preble County Probate Court at 101 E. Main Street in Eaton, OH 45320 is the main source for genealogy records. The court holds birth and death records from 1867 through 1908. Marriage records go back to 1808. Probate files also start at 1808. That is over 215 years of marriage data for this one county.
The marriage books are one of the most popular genealogy resources here. Each entry has the names of the bride and groom, the date of the license, and usually the name of the minister or justice who performed the ceremony. Older books sometimes note ages and birthplaces. Probate records include wills, estate inventories, and guardianship papers. A good will can name every member of a family. Estate inventories show what a person owned at death, from farm tools to livestock to kitchen pots. Guardianship papers reveal who took care of minor children when parents died.
Adoption records at the Preble County Probate Court have restricted access under Ohio Revised Code Section 3705.126. The Probate Court handles certified copy requests for marriage and probate records. You can visit in person or ask about mail options. County offices set their own copy fees, so call ahead to find out what it costs. The state charges $21.50 per search for birth and death records through the Ohio Department of Health per ORC 3705.24, but that covers records after 1908 only.
Because Preble County sits on the Indiana state line, some families had members on both sides. If you can not find a marriage or birth record in Preble County, check Wayne County or Randolph County in Indiana. Cross-border families were common in this region during the 1800s and early 1900s.
Vital Records for Preble County
The state took over vital record keeping from Ohio counties on December 20, 1908. For Preble County births and deaths after that date, go through the Ohio Department of Health. You can order certificates online or by mail. Death records between 1908 and 1953 sit with the Ohio History Connection archives in Columbus.
Before 1867, Ohio had no requirement for civil birth or death registration. Preble County records from that early period are scarce. You will need to check church registers, family bibles, cemetery stones, and newspaper notices for births and deaths before that year. The Ohio History Connection Vital Records Guide lays out which office holds each record type by date. Under ORC Chapter 3705, birth certificates must be filed within ten days of birth per Section 3705.09.

These are especially useful for Civil War research, since many Preble County men served.
