The majority cemetery inscriptions in the county of Columbiana have been copied by the local chapter of the Ohio Genealogical Society. Understand that this is a very early county and over time stones have gone missing for a variety of reasons. The copies of these records is also located at the library in Lisbon.
When planning to visit the graveyard be sure to check for a care taker of the records for the cemetery you are looking for your ancestor. They often provide valuable clues to your families ancestry.
Good luck in your family search.
