    Can a DNA test differentiate between a females maternal grandfather and maternal
    grand uncle, the grandfathers brother.
    And also can a DNA test differentiate between this same females paternal grandfather and
    paternal grand uncle.
    In otherwords can this females paternal and maternal grandfather be confirmed by testing
    her mother and father ?

    Yes. A father and an uncle have different DNA. Which one is which can therefore be determined.
