Bulgarian ruler

Kuber (also Kouber or Kuver) was a Bulgar leader who, according to the Miracles of Saint Demetrius, liberated a mixed Bulgar and Byzantine Christian population in the 670s, whose ancestors had been transferred from the Eastern Roman Empire to the Syrmia region in Pannonia by the Avars 60 years earlier. According to a scholarly theory, he was a son of Kubrat, brother of Khan Asparukh and member of the Dulo clan.

Ernak was the last known ruler of the Huns, and the third son of Attila. After Attila's death in AD 453, his Empire crumbled and its remains were ruled by his three sons, Ellac, Dengizich and Ernak. He succeeded his older brother Ellac in AD 454, and probably ruled simultaneously over Huns in dual kingship with his brother Dengizich, but in separate divisions in separate lands.

Alcek or Alzeco was allegedly a son of Kubrat and led the Bulgars to Ravenna that later settled in the villages of Gallo Matese, Sepino, Boiano and Isernia in the Matese mountains of southern Italy. 200px|thumbnail|right|3 shows the Bulgars of Alzeco moving along Italy. 4 shows the earlier Pannonian Bulgars of Alciocus.

Avitohol (153–353?) is the first name in the Nominalia of the Bulgarian khans. Little is known about him. According to the document he is from the Dulo clan and most probably was considered and respected as the forefather of the khans. Some researchers claim that Avitohol was identical with Attila the Hun who was succeeded by his son Ernak or Irnik (the second name mentioned in the Nominalia). Others suggests that Avitohol was a semi-legendary ruler who may have been either a descendant or an ancestor of Attila (see Dulo clan).
