[Архівовано 10 квітня 2016 у Wayback Machine.]: "Yervanduni is the name given to a family whose members were appointed by the Medes and Persians as governors in Armenia over the period 585 - 200 B.C. At least four of these governors were named Yervand. Their ethnic background is not clear. Most now believe the Urartuan and Armenian ethnicities to have been distinct, and it is not certain from which culture the Yervandunis originated. The Yervandunis were related somehow to the Persians, if not by blood, at least through bonds of marriage."
