Since September 2018, the Mercer County, Ohio GenWeb coordinators are Elaine Mihm Geyer and Kyla Cathey. We hope this site can help you trace your family history.
The Mercer County GenWeb Project is part of the OHGenWeb Project and USGenWeb Project. The goal of both projects is to help people search for their ancestors, for free. You can find additional states and counties on those websites.
Neither this website, nor the USGenWeb Project, have any affiliation with the governments of Mercer County or Ohio.
We will update frequently, so check the list below to see what's new.
Thanks to previous Mercer County Coordinator Carol Montrose for her dedicated work, and to all of the dedicated volunteers who have submitted information over the years.
October 2020:

- In the works: More obituaries; county history; more biographies; index and some transcriptions of Mercer County wills.
Do you have family history in Mercer County, Ohio? We're looking for records, military service information, obituaries, photos, biographies and more, and we need your help. Send any information to Kyla Cathey.
