Ay

Ay is believed to be the father of Nefertiti. the wife of Akhenaten. When Tutankhamun died, his powerful vizier Ay quickly stepped in and assumed kingship, despite fact that general Horemhab was the designated heir. Manetho assigned Armais with a reign for 4-5 years, which usually has been assigned to Ay instead, based on his known highest date of 4 years. It is now believed that the assignation of Armais to Horemhab was correct, but the number of years should be raised by ten. This leaves Ay unaccounted for by Manetho, unless one of the three(!) Akenchereses could somehow be assigned to Ay.
