Yohannan VIII Hormizd
According to his autobiography, Yohannan Hormizd was born in 1760 in Alqosh to an Assyrian family. His father, the deacon Hanna (Yohannan), was the brother of the Mosul patriarch Eliya XII Denha (1722–78).
Hormizd III
The Arsacid ruler of Caucasian Albania, Vache II (), who was the nephew of the two brothers through his mother, and had been forced to convert to Zoroastrianism by Yazdegerd II, took advantage of the dispute by declaring independence and reverting to Christianity. Peroz later went to the domains of the Hephthalite monarch, who agreed to him support with soldiers in his struggle for the throne. In 459, Peroz, with Hephthalite and Mihranid assistance, led an army against Hormizd and defeated him. According to some sources, Hormizd was pardoned and spared by his brother. However, this is most likely a legend, which is disproved by other sources, that states Peroz had Hormizd and three members of his family killed. No coins minted during Hormizd's reign has been found.
