Horbaef was a son of Pharaoh Khufu and an unknown woman. He married his half-sister Meresankh II, and they had two daughters, Nefertkau III and Nebty-tepites. They may have also had one son called Djaty. After Horbaef's death, his widow Meresankh married a pharaoh, her other half-brother, either Djedefra or Khafra, and thus she became a queen. It's possible that Djaty was a son of Meresankh's second husband because he had a title "king's son of his body", and Horbaef was a prince but never a king.
Horbaef was buried in mastaba G 7410-7420 at Giza. Meresankh was also buried there.
