Manetho's list was probably from Lower Egypt. He included kings from the Third Intermediate Period, even such short-lived kings like Amenemnisu (5 years) and Osochor (6 years). But he left out the kings from Thebes, such as Osorkon III, Takelot III, Harsiese A and Pinedjem I and kings from Middle Egypt like Peftjaubast of Herakleopolis. Manetho's information must have come from a local city's temple library in the River Nile Delta. The Middle and Upper Egyptian Pharaohs did not control this part of the Delta; which is why they are left out of Manetho's king-list.
