1) (fl. 1400–1340 BC)
Chief wife of Amenhotep IIIand daughter of Yuyaand Tuya. She was already married in year 2 of the reign and is depicted prominently on many monuments. She was the mother of Akhenaten and probably his elder brother, the crown prince Thutmose, who predeceased his father, as well as several daughters, notably Sitamun, who married her father; Henuttaneb; Isis; and Nebetah. Tiy survived into the reign of her son and is depicted at Amarna with a Princess Baketaten, who may have been a daughter or granddaughter. Her original burial place is uncertain, and some of her funerary equipment was apparently reused in tomb KV55 in the Valley of the Kings. A previously unidentified female mummy in the royal cache has recently been suggested to be that of the queen.
2) (fl. 1370–1323 BC)
Wife of Ay. She first appears during the Amarna Period, when she is described as the nurse of Nefertiti. It has been conjectured that Ay was the father of Nefertiti, in which case Tiy would be her stepmother. She is later depicted as Ay’s queen after he ascended the throne, which makes it unlikely that he married Ankhesenamun.
