Tigranes the Great
The first attested member of the family is thought to be Mithrobarzanes in 69 B.C, the viceroy of Tigranes the Great in Sophene. During the reign of the Arsacid family over Armenia (Arshakuni), the family ruled the princely estates of Greater and Lesser Aghbak in Vaspurakan, southeast of Lake Van, gradually annexing the surrounding territory.
