If the beneficiary of an insurance policy passes can unclaimed property of the of insurance holder be inherited by the beneficiary children.

My father was made the beneficiary of his uncle who has passed, My father recently passed as well. It has been discovered that his uncle who has never been married and have no children has some unclaimed property held by the state, as well as a small piece of property still in his name. Am I considered an heir of the unclaimed property? I have both my dad's and my grand uncle's death certificates as well as my grand uncle's insurance documents proving that my father was made his beneficiary. My sister and I would like to claim our uncle's unclaimed property that is being held with the State of GA and have the property deeds transferred over in our names.
