The time period was from the 1780's and up. A large part of Ohio was offered up to Revolutionary War soldiers in 40 Acre or so plots. A couple of land speculator companies bought huge parcels for resale. The area was predominately settled thru PA and KY and by the Ohio River. By 1801, Ohio was a state. Eckart's book The Frontiersman goes into great detail about this area thru historical fiction using diary excerpts of Simon Girty, Simon Kenton and many others. It's very accurate and can't be put down for long. Simon Kenton's Shawnee name translated into The man who's gun is always loaded. After years of skirmish and retaliation fighting, Kenton was feared as a god by the Shawnee. I HIGHLY recommend this book!
