Chanina bar Mar HaKohen

Gaon of Sura 610-614

Maternal grandfather of Bustenai

Interpreted dream for Hormuzd, King of Persia, who had slain all living members of the House of David, including the Exilarch Chanina (not to be confused with Chanina bar Mar Hacohen, who was the father-in-law of Chanina the Exilarch), leaving only the Exilarch's unborn son (Bustenai) in utero with his daughter (i.e., the daughter of Chanina bar Mar). The identity of their names, along with the general popularity of similar names (Chaninai, Achunai, Chananya) at the time, results in many people erroneously concluding that Chanania hacohen bar Chaninai of Nehar Pekod was the son of Bustenai (or even Bustenai himself), rather than the grandson of Bustenai through Bustenai's daughter. Bustenai, being of the House of David, could not have a son who was a kohain.
