Dodson and Hilton argue that Neferhetepes is not given the title of king's wife in later documents pertaining to her mortuary cult, although they note that this absence is inconclusive. They propose that Userkaf's queen may have been Khentkaus I, a hypothesis shared by Selim Hassan. Clayton and Rosalie and Anthony David concur, further positing that Khentkaus I was Menkaure's daughter. Bernhard Grdseloff argues that Userkaf, as a descendant of pharaoh Djedefre marrying a woman from the main royal line—that of Khafre and Menkaure—could have unified two rival factions within the royal family and ended possible dynastic struggles. Alternatively, Userkaf could have been the high priest of Ra before ascending the throne, giving him sufficient influence to marry Shepseskaf's widow in the person of Khentkaus I.
