The remains of Tutankamun’s Parents -- Akhenaten, and the mummy only identified as “The Younger Lady” -- and his grandparents, Queen Tiye and Amenhotep III. It was recently proven that this “Younger Lady” mummy is in fact Tutankamun’s mother, and a full sister to Akhenaten. Thus King Tut only had one set of grandparents.
King Tut's still-born baby girl found in his tomb. DNA tests also found she had Marfan Syndrome. One other baby was found w/the king that was much smaller then this one. These two tiny babies are the only examples of mummified fetuses in ancient Egypt
