This would mean that Akhenaten did marry his own sister and that he and Nefertiti are the parents of Tutankhamun. Furthermore, Nefertiti, who may have survived her husband, may be identical with Smenkhare and may have adopted this name if she took over the reign after Akhenaten's death (and having her daughter move into her official roles of chief priestess and 'wife'). All this is not proven, but should be mentioned as a further plausible scenario.[7] One difficulty posed by this identification is the mummy's age at death, because Nefertiti gave birth to Meritaten no later than year 1 of Akhenaten's reign and there is evidence that she was still alive during year 16.
