Tutankhamen was the son of Pharaoh Akenaten and his wife, Kiya. Akenaten’s Chief Wife, Nefertiti, was Tutankhamen’s stepmother as well as his mother-in-law. You have to know that Egyptian rulers often married their siblings to keep the royal line going. It was a way to keep the throne safe.
Tutankhamen married Akenaten and Nefertiti’s daughter, Ankhesanamum. So therefore, if anyone is confused, Tut married his half-sister.
Nefertari, is not related to Tutankhamen, unless she is related to Nefertiti. Since there is no proof of her being related to Nefertiti, we have to assume that she is not related to Tut either. Of course, if she was related to Akenaten or Kiya, she would be related to Tut as well, but no proof of that has been found either.
As for the age of these people, it really depends on when you’re looking them up in history. Rameses II lived to be in his nineties, which is doing extremely well for that time period. Egyptians during that time only lived to be in their mid-thirties! He outlived many of his sons and his favorite wife, Nefertari. King Tut died early in life, about 18 or 19 years of age. Nefertiti hasn’t been found yet. People have many ideas of what happened to her, but so far, without her body and tomb, we can’t have any real answers. Nerfertari, on the other hand died somewhere in her mid to upper thirties.
I hope this answers the questions I have been asked. If there are any more, I would be willing to hear them and answer to the best of my ability. With new questions brings more knowledge to me, since sometimes I have to look them up myself! 🙂
