It has been proposed that Laodice, wife of Mithridates III, was a daughter of the Seleucid King Antiochus IV Epiphanes. However, Mithradates III died before Antiochos IV had children. This proposition is based on the assumption that the sister of Alexander Balas who appeared in Rome with him in 153 BC as a genuine daughter of Antiochus IV Epiphanes was also the Laodice who married Mithridates III. Laodice, sister of Alexander Balas, may have married Mithridates V. The background of the Mithridates III's wife remains unknown.
