Probate with Will within intestate probate.

You will need to see your father's former girlfriend's will to see if he will inherit. Often wills include a provision that states that the person must survive the deceased by a period of time in order to take, for instance 30 or 60 days. If the will does have that provision, your father's estate would not receive any of her estate assets. Also, depending on the age of any children that she may have, they may be able to take against the will as well. I would suggest you get a copy of the former girlfriend's will to a local attorney for review. The will may also name a back up executor. If it does not, her family may apply. If she has no family you may apply and see if you can be appointed as her executor. The next question is independent of your father's former girlfriend's estate, your father may also have assets that need probated. You did not indicate if he had a will or not. If he does not, Ohio law provides how the assets should be distributed.
