An inscription near the entrance of the mastaba details the biography of Ptahshepses, similar to Weni the Elder's and Harkhuf's; however, the upper portions of the biography are missing so the beginning of each line is unknown. From the reliefs throughout the complex, he is given several titles:
The count, the sole companion... the keeper of the headdress... the favorite of his Lord... the chief justice, the vizier, the overseer of all the works of the King, the servant of the throne, the lector-priest... the revered one by his lord, the overseer of the Two Chambers of the King's ornament, the count, the sole companion, the lector-priest Ptahshepses.[4]
Additionally, he is called “barber of the Great House” and “manicure of the Great House.”[5] These roles were a great honor because they required touching the king, a religious incarnation himself. Ptahshepses's high social rank is also supported by three distinct statues in the mastaba's chapel, which suggest his roles as an official, as a priest, and as a private individual. Many of the mastaba's features, including the granary and treasury magazines, the boat room, and two boat pits outside of the complex suggest inspiration from royal architecture. The location of the mastaba, almost equidistant from and in front of Sahure's and Niuserre's pyramid complexes on the desert plateau also suggest a deliberate attempt at associating him with royalty.
Ptahshepses married King Nyuserre's daughter, Khamerernebty. Their five children are mentioned in the tomb: sons Ptahshepses, Kahotep, Qednes and Hemakhti, and daughter Meritites, who had the title “King's Daughter”, even though being only the granddaughter of a king.[6]
The princess's sarcophagus logistically could not have been moved into the burial chamber of Ptashepses's mastaba by the narrow descending passage. Ludwig Borchardt discovered Khamerernebty's own mastaba near Niuserre's pyramid complex. Therefore, the princess's sarcophagus must have been placed in Ptahshepses's burial chamber when the mastaba was being built. Additionally, the princess's name is found recorded by the builders on the blocks used to construct the core of the mastaba. This enables Egyptologists to date the beginning of the construction of Ptahshepses' mastaba from before the tenth regnal year until the thirtieth regnal year of king Niuserre.
