Ancient germans in antiquity claimed descendance from Mannus "son of Tuisto " identical with Man-Isttu-Su king of Agade and son - or rather grandson through Hishep-Ratep - of Sharrukínu,who ruled there from about 2079 up to 2064 b.c..
He in my opinion and according to chronicles was succeeded by the family of Asshe-Megra-yan-Na meaning Ninos of Assyria in antique sources : Nayan of Asshe-Awar . He is called by greeks Hermés Trismegistos and by aigyptians Ga-Hawat-Te-ya or T'hot ( Te-Hawat ).
His wife was Semiramis who according to legends after the death of his husband pretended herself to a man in the name of her son and ruled in Assyria for many years,who having in view may possibly be Narám-Sien successor of the previous sometimes called his brother or nephew or son,that is na-Rám-Siem - S'emi-Rámi mother.
Tradition says that Asshemegrayanna's wife was Dewanna-He daughter of Awar-Ga-Ka-Ba Awa-Sharra'ale,that is his sister,so it is likely that Narám-Sien is identical with en-He-Duanna daughter of Sharru-Kínu,mother of Sha'a-ya-la that is of Sha-Arka-a-Li-Sharri .
Their tribe spoke later dialects like today's Corean and similar ones like for example some andean languages of chimu and related tribes,while levites in their reign were descendants of Ar-Ge-Mar-Ram-Ma speaking - mainly north- - ge'rmán dialects. German name thus in this contects applied to tribes of hermions or herminons or hermundurs,of ingaevons ans istvaevons and to others including mainly gots may come from the names of Asshe-Megra-yan-Na : Ga-Herm-Mann and variations.
It is sure however that there were already germans before them too who descended from Te-Geranma-Ha,brother of A'as-Shekanned-Za and of Ar-Awab-Pat-Te,son of Ag-Ayammarra son of Awab-Pat-Te,ancestor of iturai tribe ,founders of grammatei sect in Iudaia identical with zélóta after converting to "iudaism" in the days of the usurper family of Hasamonaians,likely speaking in those times still imrágen language, like that in the region of E-Shen-Ner-Gal-Ra until today ( Senegal ), related to aigyptian.
