I really find Prince Khaemweset (or however you spell it
He was the 4th son of Ramses II. His mother was Queen Isetnofret.
Titles: King’s Son of his Body, Sem-Priest of Ptah, High Priest of Ptah in Memphis, Executive at the Head of the Two Lands.
He apparently was crown-prince from year 50 to 55.
He had a rather interesting career. He is mentioned as one of the first archeologists
Laclant wrote an article about the discovery of an inscription by the son of Ramses II, Khaemwaset, in the debris between the south face of the pyramid of Pepi I and the tombs of his wives. The text mentions how Khaemwaset found the monument of Pepi I in a ruined condition.
I have only seen this summary (not read the article).
Khaemweset also built a monument at Saqqara from what I have read.
Some think that his tomb may still be found somewhere in Saqqara. I have seen an inscription showing the preparation of offerings and it may come from his tomb. I think that for a while people thought Khaemweset may have been buried at the Serapeum, but I'm not sure that is still the concensus.
The name of the wife of Khaemweset is not known. There is a statue of a fanbearer named Khaemwaset from this period with his wife Renpetenopet. I have always wondered if this was the prince and his wife.
He is known to have had two sons and a daughter. His sons are named Ramses and Hori, and the daughter is Isetnofret.
Iset-nofret may have married her uncle Merneptah and become queen (but that's not certain; this queen could also be the daughter of Ramses.)
Hori actually becomes High Priest of Ptah after his father. His tomb has never been found either, but is thought to have been located at Saqqara.
