Mahoning County, Ohio Online Historical Directories

Expand your research by checking out the Ohio Online Historical Newspapers here.


Links to directories at New England Historic Genealogical Society (NEHGS) are to the images themselves, which are browsable.  Non-subscribers will not be able to view these. Non-subscribers can, however, use the search engine and see a listing of possible results (but no images or further details).  To search by keyword, go to the Digital Archive & Library search engine on this page (it is the second search box).  For more information on how to access subscription websites, read Number 5 on my FAQs page.
