ベヒストゥン碑文
The traditional view based on archaeological research and the genealogy given in the Behistun Inscription and by Herodotus holds that Cyrus the Great was an Achaemenid. However, M. Waters has suggested that Cyrus is unrelated to the Achaemenids or Darius the Great and that his family was of Teispid and Anshanite origin instead of Achaemenid.
