Two suggestions for SIP. Dynasty 13 was ruling from Itj-Tawy (possibly Memphis at first) and 14 from Xois in the delta. The invading Hyksos (15) made Avaris their capital in about 1655. Dynasty 16 is today thought to have come from Thebes like 17 which started a liberation war that finally drove out the Hyksos from Egypt. 120-130 kings' names are known and many are still to be put in position.
