Etymology.
According to some researchers, is the name was brought by the families from Kusakan town in Turkey, which was destroyed by the Mongols in the 13th century. There are also specific areals of this name in the territory of Azerbaijan: Kosakan (Zangilan), and Kusekana / Kusəkəran (Lerik). In Turkey, the Kösedağ (Kosadagh) mountain has been registered in the 80 km from the Sivas. The "Kosakan" name is made from the word "kosak" from ancient Turkic languages ("closed, combined") and -"an" suffix ("place, location"); it was formed in connection with the transition of the people to sedentary life.
