An archival document mentions Mir Aziz Khan as the brother of Mir Abbas Beg. Elsewhere, Mir Abbas Beg offers to entrust either his brother or his son to Russia to show his allegiance. Mammadova named Mir Abbas as the son of Seyyed Abbas, but Khansuvarov believed that Mir Abbas was the grandson of Seyyed Abbas. His father's name was Seyyed Yūsef, who succeeded his grandfather in religious affairs. Seyyed Yūsef was buried at Yuxarı Nüvədi village of Lankaran.
