The two women were belived to be Hetephernebti, who they belived to be his Queen, and Inetkawes, who they belived to be his daughter. From what i understand of the reading that he was a good person that everyone liked.
contribution
Their where many things taht Djoser did one was the rebuilting of the temple of Khnum on the island of elphuntinc. He was also builting a tomb in abydos, but he died before it could be built. His most famous building was the step pyramid that he was buried in. He also did some military expeditions, but they were not major one they were to just stop some locals that were causing problems.
Downfall
Historians are not sure how he died so it is undetermined. Egypt lived on until the end of the thrid dynesty.
