Here is a brief description of the House of Vidṛna (Hydarnes), synthesizing the accounts of classical historians, royal Achaemenid inscriptions, and modern scholarship such as the Encyclopaedia Iranica.

Origins and Elevation to the "Seven"

According to Darius the Great (The Behistun Inscription, c. 515 BCE): The house was founded by Vidṛna, son of Bagābigna. He is officially recorded as one of the key figures who helped Darius crush the rebellion of Phraortes in Media.
According to Herodotus (Histories, 5th C. BCE): The family gained its elite status because Hydarnes the Elder was one of the "Seven Persians" who assassinated the Magian usurper Gaumata. As a reward, the House of Hydarnes became one of the Seven Great Noble Houses of the empire, enjoying immense privileges, including direct access to the King of Kings and hereditary lands.

Military Dominance and Imperial Intermarriage

According to Herodotus: The second generation of the house represented the pinnacle of Achaemenid military elite. Hydarnes' son, Hydarnes the Younger, was appointed commander of the "Ten Thousand Immortals," the premier infantry unit of the Persian army, which he led during Xerxes’ invasion of Greece in 480 BCE.
According to Ctesias of Cnidus (Persica, early 4th C. BCE): The family's power was cemented by intense intermarriage with the Achaemenid royal family. Ctesias details how a later descendant, also named Hydarnes, married his children into the royal line—most notably his daughter Stateira, who married King Artaxerxes II, and his son Teritouchmes, who married the king's sister, Amestris.
According to Encyclopaedia Iranica: This extreme proximity to the throne eventually made the family a threat. Iranica notes that royal jealousy and court intrigue (particularly driven by the queen mother, Parysatis) led to a massive purge of the family in the late 5th century BCE, though the branch ruling Armenia survived.

Later Cadet Houses and Transition to the Kings of Armenia (The Orontids/Ervandunis)

According to Xenophon (Anabasis, early 4th C. BCE): Following the purge of the main branch, the surviving Armenian branch thrived. Xenophon describes Orontes I (Ervand) as the powerful Satrap of Armenia who was married to Rhodogune, the daughter of Artaxerxes II.
According to Strabo (Geography, 1st C. BCE / 1st C. CE): Strabo provides the explicit genealogical link connecting the later rulers of Armenia back to the original Achaemenid conspiracy. He writes that Orontes, the ruler of Armenia, was a direct descendant of "Hydarnes, one of the seven Persians."
According to Encyclopaedia Iranica: Modern scholarship categorizes this surviving branch as the Orontid Dynasty (or Ervanduni in Armenian). Iranica emphasizes that after the fall of the Achaemenid Empire to Alexander the Great (330 BCE), the House of Vidṛna did not collapse. Instead, they successfully transitioned from Persian provincial governors into the first independent, Hellenistic Kings of Armenia, maintaining their rule until around 200 BCE.
