Ohio Genealogy Resources

Through the years, I’ve needed to do some research in Ohio so I thought it was time I created a list of resources for this state. Many of these links are combos of some free access and some membership or subscription required. Many of these sites have online digital collections. Cyndi’s List has tons of Ohio links covering about every category you could think of.

As always, be sure to check for local genealogy and historical societies in towns of interest and don’t forget to contact the local public library there to inquire about unique holdings that they might have.

The links are strictly in ABC order, so you’ll need to scan the titles to find sites of interest. These should help get you started with your Ohio research!

  1. Wonderful list, all in one place. Since my husband has lots and lots of Ohio ancestors, I’ve used some of these resources but not others. Gonna be a lot of clicking going on this weekend, thanks to you!

  2. This is a great list, Linda. It’s hard to get them all for the whole state, though, isn’t it?!

    The State Archives Library is in the same building with Ohio History Connection and while the OHC is a membership organization, there is no charge to go up to the Archives Library. Catalog and information here: https://www.ohiohistory.org/learn/archives-library.

    Also, for many years, the State Library of Ohio had a genealogy section. They closed that section and sent most of the books to the Columbus Metropolitan Library. However, the SLO continues to have some of the special censuses (agricultural, etc.) including, surprisingly, for other states.

    Columbus Metropolitan Library has resources for many other states, too, as well as other countries.
