Merefnebef, also called Unisankh and Fefi (fl. c.
He was a keeper of the head ornaments, and was privy to the secrets of the House of the Morning.
He may have become a vizier late in his career and those titles are recorded on the façade of his tomb.
The mastaba of Merefnebef is located to the west of the Step Pyramid of Djoser.
At least one of Merefnebef's sons had his fathers' and brothers images removed, as well as altering his father's titles in particular those of "Honoured by the king" by erasing the word "king" or even replacing it with the word "desert".
