Wadi Hammamat
Jürgen von Beckerath tentatively identified Neferkare II with the prenomen "Wadjkare" ("Flourishing is the Ka of Ra"), which is attested on a graffito from the Wadi Hammamat contemporary with First Intermediate Period. This identification is seemingly rejected by Baker who makes no mention of any attestion for Neferkare II beyond the Abydos king list, while Thomas Schneider relates Wadjkare to either Neferkare II or Neferirkare II.
