Königspapyrus Turin
He is definitely attested only on the Turin King List, since he is not known by any archaeological find. It is highly unlikely that Neferkare VIII and the enigmatic king "Ka-nefer-re" mentioned in the tomb of the nomarch Ankhtifi are the same person, and it is somewhat more likely that Kaneferre should rather be identified with Neferkare VII of the previous 9th Dynasty.
