This helpful information is available by searching on Crawford County Ohio USA on Family Search’s Research Wiki. This wiki is my first stop in researching any genealogical project, especially for the United States.

Beginning Dates for Vital Records
In addition to when county’s were created and what county they were created from, most of the US State County pages include a Records Date Chart. It shows when various types of records, including vital records, began to be collected by the local government of the county. I’ve found this to be invaluable in my research. It tells me whether I should bother looking for a vital record at all.
