Y-DNA Haplogroup C-V20 Magog literally meaning "From Gog" in a similar pattern to the name Mitzraim. The nation that originally came from Georgia, a region between the Black and Caspian Seas south of the Caucasus Mountains.
Arab writers referred to the Great Wall of China as the 'wall of al Magog' (Rabbi Aaron Marcus, Kesseth HaSofer, p. 112a) and this is reiterated in Papal sources noting that Magog may denote the Mongols, whose name they said came from Magogoli which they claimed was a corruption of Magog. Other ancient sources make identification of Magog as living to the north of the Black Sea (Yov'loth 9:8).
Some sources identify Magog with Germania (Targum Yonathan; Targum on 1 Chronicles 1:5; Pesikta Zutratha). Others identify them with the Goths (Yerushalmi, Megillah 1:9) the Heberite people who otherwise named themselves after their Scythian masters, in what is now southern Russia. Hence some identified Magog with Scythia (Josephus; Yoma 10a, according to Rabbenu Chananel; Arukh s.v. Germamia). Ancient histories state that the Scythians came from Asia, driven by the Massagetae (cf. Meshekh), and settling near the Cimerians (Herodotus 4:11; see note on Genesis 10:2, 'Gomer'). Linguistically, the Scythians were related to the Iranians, and hence, to the Persians and the Medes. It is therefore no surprise that Herodotus thought the Germanians to be a Persian tribe (Herodotus 1:125). Interestingly enough Angalo Saxon legends claim Gogmagog as an ancient ancestor. Gog Magog were traditionally locked behind copper and iron gates by Alexander the Great. Two Giant effigies of them are kept behind the gates of guildhall in London.
