Alternatively, Nicolas Grimal, Peter Clayton and Michael Rice propose that Userkaf was the son of a Neferhetepes, whom Grimal, Giovanna Magi and Rice see as a daughter of Djedefre and Hetepheres II. The identity of Neferhetepes's husband in this hypothesis is unknown, but Grimal conjectures that he may have been the "priest of Ra, lord of Sakhebu", mentioned in Westcar papyrus. Aidan Dodson and Dyan Hilton propose that Neferhetepes was buried in the pyramid next to that of Userkaf, which is believed to have belonged to a woman of the same name.
