Ramesses I
Paser I was the Viceroy of Kush during the reigns of Ay and likely Horemheb. Reisner mentions that the only datable inscriptions for Paser belong to the reign of Ay. The next known Viceroy however is Amenemopet, who is dated to the reign of Seti I. Hence it's possible that Paser I served during the reigns of Ay, Horemheb (and maybe even Ramesses I?).
