Kazarig
Kazarig, was the name of a dynasty of rulers in the Land of Kedar. The first Khazarig was, according to Sandilch, a son of Ernakh, after whom the Kutrigurs were named. Ernakh's other son was Utig after whom Sandilch's own Utigurs were named.
Perhaps unrelated, Kozar, the name of a Khazar ancestor in the Khazar correspondence, could mean "Goat-Herder" in Slavonic languages.
Bar Hebraeus
According to Bar Hebraeus and the Chronicle of Michael the Syrian, the name Kazarig was later adopted by one of three brothers who came from the Imaon mountains to rule Hunnish tribes in the East European grasslands in 583. Kotzarig's subjects became known as Khazars. His brother Bulgarios with 10,000 men acquired Dacia from Maurice (emperor). The fate of the third brother is not mentioned.There is a frequently drawn parallel between these three brothers and the three brothers Shchek, Khoryv (Carpathia) and Kyi to whom the Khazars are said to be related.
