 Even though Isesi-ankh bore the title of "King's son", the Egyptologists Michel Baud and Bettina Schmitz have shown that this filiation was probably fictitious, being used only as an honorary title.In particular, inscriptions found on the construction blocks of his mastaba give one of his titles as "Seal bearer of the king Isesi ankh", while Baud argues that had he really been the son of a king, this title would have been "Seal bearer of the king, king's son, Isesi ankh".Consequently, Isesi-ankh's father was likely not Djedkare Isesi.
