In Assyrian they are the Ashkuz and much has been written about them. The Greek word Scythia is accepted as being derived from the Assyrian Ashkuz.
Among the Arsacids, the Scythian (Kazakh-Nogay) Ashkenaz nation were also known as “Tor-Gom” because they were the offspring of Tiras and Gomer whose descendants belong to Y-DNA Haplogroup CM217. Juansher's "Concise History of the Georgians" goes into detail about how they threw off the yoke of the Nimrodians.
Written between 458 and 464, Egishe mentions that to the north of the land Chora (the Derbend pass) lived the Hunnic Hajlandur (hajlandur'k) nation. They already had a 'royal clan', that is, tribal aristocracy, and Christianity was beginning to spread among them. They maintained connections with the Kushans. In 454 a young Hajlandur at the service of the Persian ruler Yazdgird II (438-457) ran away to the Kushans, warned them about the forthcoming Persian attack and thus contributed to the victory of the Kushans. According to A.D. Gadlo the identification of the Hajlandurs with the Aguandurs is confirmed by a fragment of the history of Egishe, preserved in the 10-th century Armenian author Moses Kagankatvaci, where the country of the Hajlandurs is called Aguandria (Aluandria), that is, country of the tribe Aguandur. These were the Alans often confused with the Ossetian Hebrews (called Khazars by Juansher).
