OK.... If you have the Ohio Title and it has the proper VIN and description of the car AND it has no other names on it that might be owners or hold some interest in the car, and it's signed by the owner, just take it down to the BMV and register it. You will need to pay the sales tax, transfer fees, license fee and probably prove you have insurance.
Lienholder- a person or business that has registered their name on the title of the vehicle that owns some interest in the vehicle. This typically is the loan company. If this appears on a title, it is a loan that must be repaid to that person and the only way to register the car will be for the lienholder to sign the title saying the loan was paid and they no longer hold an interest in the car.
Good luck, I think everything will work out...
