Discover Your Delaware Ancestors

Delaware County, located near the center of Ohio, was formed in 1808 from land taken from Franklin County. The settlement of Delaware was established as the county seat.  Over the years Delaware County has produced numerous well known political figures, the most prominent  being Rutherford B. Hayes, 19th President of the United States. 

The Delaware County Genealogical Society is dedicated to preserving our rich history for future generations.  Numerous volunteers have donated countless hours to provide the information available through this website.   We hope you find this website useful and visit our research Library soon.
