In short, no. A POA is only valid while the principal (person giving authority) is still alive. From the facts provided it sounds like you are stuck going through probate for the real estate. As for who gets the property, since there is no Will, the Ohio rules of descent and distribution determine who gets what. (O.R.C. 2105.06)

You may want to sit down with an attorney to review your situation and assist you. Administering a probate estate without legal counsel can be very difficult and time consuming.
Best of luck.
