[2] His father's name was Aslamaz and he had two younger brothers, Vakhushti and Gorjasbi (Mansur), who also held prominent positions like him.

[3] He furthermore had a known younger cousin named Qaplan Baratashili-Orbelishvili (Orbeliani) (?–1671), who had fled to mainland Iran in the early 17th century after the death of his father Elizbar Baratashvili-Orbelishvili, the latter being therefore Otar's uncle.

[4] Otar was mentioned for the first time in the Iranian sources in 1626, when he held the function of darugha (prefect) of New Julfa, having succeeded Mirman Mirimanidze (Safiqoli Khan) on this post.

[1] Later, in 1649, during the reign of king Abbas II (r. 1562–1666), he was given the governorship of Qandahar in the easternmost territories, as well as the honorary name of Zu al-Faqār Khan.

[5] When Qandahar was surrounded by the Mughal forces in 1653, the city nearly fell due to the protracted siege, and Otar was blamed for his soft attitude.
