Ahmose called Si-Tayit was possibly the first Viceroy of Kush. It is possible that the position was held by a son of Pharaoh Ahmose I before Ahmose called Si-Tayit was appointed Viceroy, but there is no conclusive evidence for such a Viceroy.Edwards, The Cambridge ancient history, Volumes 1-3, 2000, pg 299, 348

Before Si-Tayit the power in Kush seems to have been in the hands of a dignitary named Hormeni, who was the mayor of Hierakonpolis.

Ahmose called Si-Tayit served as Viceroy under both Ahmose I and Amenhotep I. Early in the reign of Amenhotep I, the position passed from Si-Tayit to his son Ahmose called Turo. The position of Viceroy was not hereditary, and the position did not pass to Turo's son Patjenna.Boston Museum Bulletin, VOL. LXX, 1972, NOS. 361-362
