 Grimal and Hayes further equate Sheshi with Sharek, a king whose sole attestation is found on a stone slab detailing the genealogy of Ankhefensekhmet, a priest who lived at the end of the 22nd Dynasty c. 750 BC, some 900 years after Sheshi's estimated lifetime.William Ayres Ward and the archaeologist Daphna Ben-Tor rely on seriations of the seals of Sheshi and other kings of the Second Intermediate Period to date Sheshi to the second half of the 15th Dynasty, between the great Hyksos pharaohs Khyan and Apophis.Jürgen von Beckerath is less assertive about Sheshi's identity and assigns him to his combined 15th/16th Dynasty, where he regroups Hyksos rulers whose chronological position is uncertain together with kings whom he sees as vassals of the Hyksos.
