We are the Defiance County Chapter of the Ohio Genealogical Society. Our mission is to foster an interest in genealogy and preserve local genealogical records.

The Defiance County Chapter OGS does not have its own library. However, the chapter is actively involved in maintaining and expanding the material in all three Defiance County Libraries.

We are working to preserve our history and culture with an emphasis on Defiance County, Ohio. If you have anything historical about Defiance County you would like to share with us, please attend our next meeting or contact us at the P.O. or E-mail below.
