Dulo clan
The second listed ruler is Irnik, who lived 150 years and also descended from the Dulo clan. It is generally considered that in the "Nominalia" under Irnik was considered the third son of Attila, Ernak. Vasil Zlatarski thought the identification between Irnik and Ernak pointless, and they were two different persons and families. Zlatarski pointed out, which points Runciman considered to be indisputable; if Irnik was Ernak, then both Ernak and Attila belonged to the Dulo clan, whereas, actually, no source mentions Dulo clan in connection with them; according to the "Nominalia" Irnik ruled from 437, i.e. several years before the death of Attila in 453, which is impossible. Due to be assigned a reign of 150 years, Runciman considered the inaccuracy of the date of accession as venial mistake.
