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 RecordsDeath Notices and Obituaries, and Cemeteries.
See Guardianships and Orphanages for alternative sources of birth information, including adoption records.

Roman Catholic Baptisms

HCGS has published six indexes authored by Jeffrey G. Herbert and Julie M. Ross of baptisms from the Archdiocese of Cincinnati – five indexes of over 210,000 baptisms in Hamilton County and one of 18,800 baptisms outside Hamilton County. These indexes contain for each baptism: name of child, date of baptism, father's and mother's names if available, church, and record page if available. The source materials for these works 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.
