The Jefferson County Chapter of the Ohio Genealogical Society (JCCOGS)
was formed in 1986 to support the objectives of the Ohio Genealogical Society by creating and building interest in the collection and preservation of historical and genealogical materials and records of Jefferson County and the adjoining areas of the Ohio Valley. This chapter takes an active part in the collection of records and helps to make these chapter discoveries available for use by the public in various formats. Our goal is to bring together individuals having a common interest in genealogy and/or local Jefferson County history. Persons living in Jefferson County, as well as those having roots in the county, comprise the membership.
