Name 
The possible origin of the name of khan Kotrag from the Chuvash name Kătrak and Kătrashka, which in translation means Curly, a common pre-Christian name among the Chuvash. In the Kipchak languages, the word Curly is translated as tat. Bodrә (Бөдрә) on kaz.Buyra (Бұйра). Perhaps the name Kotrag was given in honor of the great-grandfather Kobrat, who also bore the name Kotrag in honor of whom the whole tribe of Kutrigurs was named.
Procopius also recorded a genealogical legend according to which:...in the old days many Huns, called then Cimmerians, inhabited the lands I mentioned already. They all had a single king. Once one of their kings had two sons: one called Uti oghur and another called Kutri oghur. After their father's death they shared the power and gave their names to the subjected peoples, so that even nowadays some of them are called Utigurs and the others - Kutrigurs.Many researchers of Chuvash history note a common name before christian chuvash as Kutri (chu.Kăтри) - which means Curly, perhaps this name is also reflected in Procopius.
