What is "isesi-ankh"

Isesi-ankh (transliteration Izzi-ˁnḫ) was an Ancient Egyptian high official during the second half of the Fifth Dynasty, in the late 25th to mid 24th century BC. His name means "Isesi lives". He may have been a son of pharaoh Djedkare Isesi and queen Meresankh IV, although this is debated. Isesi-ankh probably lived during the reign of Djedkare Isesi and that of his successor Unas. He was buried in a mastaba tomb in north Saqqara, now ruined.
