Aside from Vaballathus, it is unclear if Zenobia had other children and their alleged identities are subject to scholarly disagreements. The image of a child named Hairan (II) appears on a seal impression with that of his brother Vaballathus; no name of a mother was engraved and the seal is undated. Odaenathus' son Herodianus is identified by Udo Hartmann with Hairan I, a son of Odaenathus who appears in Palmyrene inscriptions as early as 251. David S. Potter, on the other hand, suggested that Hairan II is the son of Zenobia and that he is Herodianus instead of Hairan I. Nathanael Andrade maintained that Hairan I, Herodianus, and Hairan II are the same person, rejecting the existence of a second Hairan.
