The mummy known as “The Younger Lady”, formally identified as the mother of king Tutankhamun and full biological sister of the mummy known as KV55 (believed by some scholars to be that of Akhenaten but not officially certified). “The Younger Lady”, is a daughter of king Amenhotep III and his Great Royal Wife, Tiye.
“The Younger Lady”, was found in tomb KV35 by archaeologist Victor Loret in 1898. She was laid out beside the mummy of her mother (Tiye) and the mummy of a young boy, possibly the young Prince Thutmose, a son of Amenhotep III and his Great Royal Wife Tiye. For a long while the mummy of Great Royal Wife Tiye simply went by “The Elder Lady”, until officially identified by a lock of hair buried within Tutankhamun’s tomb, labelled as the hair of his grandmother. This hair was a definite match for the natural hair upon Tiye’s mummy.
Various scholars and Egyptology lovers have theories of the identity of “The Younger Lady”, identifying her as a secondary wife of Akhenaten, Kiya, and some even propose she is Nefertiti herself, however…these are simply theories. As of yet “The Younger Lady” has not been formally identified, other than her biological relation to the mummies of her mother (Tiye), father (Amenhotep III), brother (KV55) and son (Tutankhamun).
