Births & Baptisms

For information on the following record repositories mentioned on this page see:
Since December 20, 1908, Ohio state law has required the recording of all births on standard birth certificate forms. Prior to that date Ohio counties and some cities began keeping birth records. Birth records at Hamilton County Probate Court run from 1863 to 1908. The City of Cincinnati also created birth records from 1874 to 1912. Many births were not recorded, but registration improved by the turn of the 20th century. Church baptismal records provide supplemental information, particularly for births prior to these dates and births not registered. Birth dates and parentage can sometimes be determined from Death Records, Death Notices and Obituaries, and Cemeteries.
See Guardianships and Orphanages for alternative sources of birth information, including adoption records.

Roman Catholic Baptisms

HCGS has just published the first index of Roman Catholic baptisms in Hamilton County - NEW Jan. 2018:
Hamilton County, Ohio Roman Catholic Baptism Records - Early – 1849.
Authored by Jeffrey G Herbert. Published 2018. This index contains the names of over 17,500 Roman Catholic baptisms recorded in Cincinnati and Hamilton County, Ohio prior to January 1850. The source materials for this work are the microfilm copies of original baptismal registers which were kept by the individual parish churches, and are stored at the Archives of the Archdiocese of Cincinnati. Although the diocese was founded in 1821, the oldest surviving records in Hamilton County are for Holy Trinity Church and date to 1834. The surviving records for the first church, St. Peter in Chains Cathedral, begin in 1839. This index contains baptismal records of all ten existing Roman Catholic Churches in Hamilton County, Ohio prior to January 1850.
Published Full Index
The full index is published in our the book and contains for each baptism: name of child, date of baptism, father's and mother's names if available, church, and record page if available.  The book is available:
Public Online Abbreviated Index

An abbreviated index is available online at the followng link that contains the name of each child and the year of baptism for each baptism:
From the record found in the abbreviated index a search can more readily be made of the published full index described above to find the actual date of baptism, parents' names, and the specific church.
NOTE: For Roman Catholic baptisms after 1849 a search will need to be conducted at the Historical Archives of the Chancery.
To obtain a copy of the original record (Protestant or Catholic)
  • For Protestant baptisms indexed in the "Selected ..." series of books visit the PLCH, CHLA or LDS Family History Center to view and copy the original baptismal records from microfilm. The source microfilms referred to in the index for the original baptismal records are available at the PLCH, CHLA, and LDS.  NOTE: The LDS is digitizing their microfilms and placing them online on their FamilySearch.org website. These are available to registered users of the website (free).  Some of the microfilms referenced in the Selected... series are now available online.  Go to the FamilySearch.org catalog search page, log into the website, click on Film/Fiche Number under Search For and enter the film number in the box.  In the resultant search if the film number has a little camera icon click on that.
