The Augustan History mentions that Odaenathus had many sons, including one named Herodes (from an earlier marriage) and another named Herennianus.[3] According to Henri Arnold Seyrig, Hairan II must be identical with Herennianus and he was an older brother of Vaballathus and did not reign.[2] Seyrig distinguishes Hairan I from the Hairan on seal RTP 736.[4] Andreas Alföldi also suggested that Septimius Herodianus is Herennianus; another seal associated with the seal of Septimius Herodianus represented a woman crowned with laurel leaf who, according to Alföldi, can only be Zenobia.[5] Hence, Septimius Herodianus is the son of Zenobia and Odaenathus.[5] In the view of Alföldi, Odaenathus's eldest son, Herodes of the Augustan History, would not have been called King of Kings during his father's lifetime and Septimius Herodianus briefly succeeded his father.[5]
