Ohio Vital Records

Ohio enacted a statute in 1856-57 that required birth, death, and marriage registration, a law that was generally disregarded. A later 1867 law again required registration of birth and death records. Some of these are extant. Two types of ‘death records’ known to be in existence before 1867 are records of cholera deaths, registered during some epidemics, and veterans’ deaths, representing only a small proportion of the deaths that occurred. The third law, which went into effect on 20 December 1908, set up the current record keeping system in Ohio.

Ohio Vital Records at rootsweb and Ohio Vital Records at FamilySearch.org, has more details regarding vital records.  

Ancestry.com and FamilySearch.org has a variety of online collections. I have included many of these in the links below.
