Pepi II Neferkare
Pepi II (also Pepy II; 2284 BC – after 2247 BC, probably either 2216 or 2184 BC) was a pharaoh of the Sixth Dynasty in Egypt's Old Kingdom who reigned from 2278 BC.
His throne name, Neferkare ("Nefer-ka-Re"), means "Beautiful is the Ka of Re".
He succeeded to the throne at age six, after the death of Merenre I.
He was traditionally thought to be the son of Pepi I and Queen Ankhesenpepi II but the South Saqqara Stone annals record that Merenre had a minimum reign of 11 years.
Several 6th dynasty royal seals and stone blocks—the latter of which were found within the funerary temple of Queen Ankhesenpepi II, the known mother of Pepi II—were discovered in the 1999/2000 excavation season at Saqqara which demonstrate that she also married Merenre after Pepi I's death and became this king's chief wife.
Inscriptions on these stone blocks give Ankhesenpepi II the royal titles of: "King's Wife of the Pyramid of Pepy I, King's Wife of the Pyramid of Merenre, King's Mother of the Pyramid of Pepy II".
Therefore, today, many Egyptologists believe that Pepi II was likely Merenre's own son.
Pepi II would, therefore, be Pepi
I's grandson while Merenre was, most likely, Pepi II's father since he is known to have married Pepi II's known mother, Queen Ankhesenpepi II.
This would also conform well with the evidence from the South Saqqara Stone which shows no coregency between the reigns of Pepi I and Merenre thus making it far more likely that Pepi II was Merenre's own son.
Pepi II's reign marked a sharp decline of the Old Kingdom.
As the power of the nomarchs grew, the power of the pharaoh declined.
With no dominant central power, local nobles began raiding each other's territories and the Old Kingdom came to an end within mere decades after the close of Pepi II's reign.
Nitocris
Nitocris  has been claimed to have been the last pharaoh of ancient Egypt's Sixth Dynasty.
Her name is found in Herodotus' "Histories" and in writings by Manetho, but her historicity is questionable.
If she was in fact a historical person, then she may have been an interregnum queen, the sister of Merenre Nemtyemsaf II and the daughter of Pepi II and Queen Neith.
Alternatively, the Egyptologist and phylologist Kim Ryholt has argued that Nitocris is legendary but derives from the historical male pharaoh Neitiqerty Siptah, who succeeded Merenre Nemtyemsaf II at the transition between the Old Kingdom and First Intermediate Period.
