Guernsey County Genealogy Lookup

Guernsey County genealogy records reach back to 1810, the year the county was formed from Belmont and Muskingum Counties. The county seat is Cambridge, where the courthouse sits on Wheeling Avenue. Researchers can find marriage, birth, death, land, court, and probate records through the Probate Court and other local offices. The Guernsey County Genealogical Society adds even more depth with their own record collections. This guide covers the key offices and resources for searching Guernsey County family history.

Guernsey County Record Sources

The Guernsey County Courthouse is at 801 Wheeling Avenue, Cambridge, OH 43725. The Probate Court keeps marriage records from 1810, birth and death records from 1867 to 1908, and probate records from 1812. The Guernsey County Recorder holds land records from 1802. That is earlier than the county's official formation, because the area had land filings under the parent counties before 1810. The Clerk of Court has court records from 1802 as well.

Divorce records and civil case files sit with the Clerk of Courts. If you need a divorce decree from Guernsey County or any civil case document, that office handles it. Most court records in Ohio are public, so access is typically straightforward.

Probate records from 1812 round out the courthouse holdings. Wills, estate papers, and guardianship documents are all at the Probate Court. Early wills from Guernsey County can name heirs, describe land, and list personal belongings. Estate inventories sometimes show what your ancestors owned down to pots, tools, and livestock. These files help paint a fuller picture of family life in the early 1800s. The Probate Court Case Files Index from the Genealogical Society covers the mid-1840s through the mid-1960s, which saves time when you need to find a specific case number or volume.

Vital Records in Guernsey County

Before 1908, county probate courts in Ohio were the main place where births and deaths got recorded. In Guernsey County, birth and death records from 1867 to 1908 are at the Probate Court. These early entries are usually short ledger notes. After December 20, 1908, the Ohio Department of Health took over vital record keeping statewide.

Birth records before 1867 were not required by law in Ohio, so you will not find them at the Probate Court. Death records from 1908 to 1953 are held by the Ohio History Connection in Columbus. Under Ohio Revised Code Chapter 3705, vital records must follow state filing guidelines. Marriage records at the Probate Court go back to 1810. Those are the oldest vital records in the county.
