Passage: Adjib's family has only partially been investigated. His parents are unknown, but it is thought that his predecessor, king Den, may have been his father. Adjib was possibly married to a woman named Betrest. On the Palermo Stone she is described as the mother of Adjib's successor, king Semerkhet. Definite evidence for that view has not yet been found. It would be expected that Adjib had sons and daughters, but their names have not been preserved in the historical record. A candidate for being a possible member of his family line is Semerkhet.

Question: What man was the ruler?
king Semerkhet
