• The Clermont County Historical Society is not the primary source of information on genealogy information. The Clermont County Genealogy Society fills this role. The Historical Society will check its archives for information we may have, but for information on deaths, marriages, cemeteries, etc. a much better source of information is the Batavia Branch of the Clermont County Library.(513-732-2128, www.clermont.lib.oh.us) and the Clermont County Genealogy Society (513-723-3423, www.rootsweb.com/~ohclecgs/).
