Origin and ethnogenesis Kurdak-Sargat Tatars are descended from the earliest Turkic settlers in the area, southern Khanty, as well as Noghay and Tobol Tatar elements (the latter date from 1580's). One characteristic is a lack of intermixing with Bukharans. If intermixing with Bukharans was present, it was with earlier Uzbeks. Kurdak Tatars have a Kipchak layer in their ethnogenesis, as is withnessed with the ethnonym Qaraqipchaq.
Sargat-Utuz Tatars are descended of the Khitans, an originally Mongolic group that later became Turkicized. They are also the descendants of the “Otuz Tatars” of the Orkhon Inscriptions.
Immigrant Volga-Ural Tatars settled among the Kurdak-Sargat Tatars in the later periods, in the late 19th and early 20th centuries.https://journals.openedition.org/monderusse/pdf/44 Ethnic processes within the Turkic population of the West Siberian plain (sixteenth-twentieth centuries)
