Happy 200th Birthday, Union County!
Our mission is to promote and nurture an interest in genealogy by providing instruction, information, and inspiration, while encouraging members and others in the development of family histories and genealogical records, for the benefit of future generations.
We are very proud of our history. We can trace our beginnings back to 1979. Our charter was granted by the Ohio Genealogical Society in 1980. Today we continue to preserve the genealogies of Union County and the surrounding area. We also welcome any one to join our society, whether or not they have Union County roots.
All in person
due to COVID-19.

Memberships expire on
December 31 of each year.
Unless otherwise noted, all meetings are held at 10am on the third Saturday of each month in the lower level of the Marysville Public Library located at 231 S. Plum St., Marysville, Ohio 43040. We do not hold meetings from December to February or in July.
We currently have two Lineage Societies. They are the Union County Pioneers and the Civil War Families of Union County, Ohio. You must be a member of the Union County Chapter of the Ohio Genealogical Society in order to join either of our societies.
We currently have several online collections that are available. These collections include an index to our obituary collection, birth registrations, birth corrections from 1856-1860, the marriage registry from 1856-1860, and children's home records from 1884-1907.
All fourteen of our townships contain multiple cemeteries. We have digitalized copies of the WPA maps for many of these cemeteries. We are working to include driving directions and brief histories of all known cemeteries to have existed in Union County.
