“I made the connections that mattered!”

Online research was great, but I wanted to learn more. With the OGS, I was able to meet people who could guide me through real source material. It’s fun, it’s challenging, it’s a puzzle I am now able to solve. Thanks OGS!

Solving the Puzzle: Why The Right Material Matters

From Lake Erie to the Ohio River, from Youngstown to Toledo, Ohio has a deep and rich history.

You might be looking for the home where your great-grandparents were born. You might be looking to find who your great-great grandmother married after her first
husband died in the Civil War. You might be looking for an old deed to find where your family’s business or home was built.

You won’t find all of that online. You can only find that by searching the right material. You can only find your past by looking at it when it was the present. We’ll teach you how to do that.
