  • Findmypast has announced that, "Over 405,000 sacramental register entries covering 103 Parishes across the Dioceses of Cincinnati are now available to search online for the first time. These new collections consist of indexes of baptisms, marriages, burials and congregational records spanning the years 1800 to 1979." Please note these are indexed transcripts rather than images, and they were provided by a third party, not by the HCGS, and may be incomplete.
  • A new Article Index for our quarterly journal The Tracer covering the years 2008 - 2018 has been added to this website.  The earlier article index covering the years of publication 1979 - 2008 remains available.
