Where Did Germany Get It's Name From?

I thought this was interesting as I read from an article called, 'The Table of Nations' by Tim Osterholm. He explains the origin of the term 'German' and how this name came to be.
   The term "German" comes from Latin (Roman) sources.  The Assyrians occupied a Mesopotamian city on the lower Tigris River called "Kir" and placed captive slaves there (also referenced in 2 Kings 16:9, Isaiah 22:5-6, Amos 1:5, 9:7).  The city was populated by the Assyrians for many years, and the inhabitants became known as "Kir-man."  The Assyrians (Kerman) were driven from their land shortly after their fall about 610 B.C.  They migrated into central Europe where they were called "German" or "Germanni," a general name used by the Romans to represent all Assyrian tribes.  The known Assyrian tribes were the Khatti (also, Chatti, Hatti and Hessian)—Chatti is still the Hebrew term for German, and Khatti was also used by the Romans to represent various Germanic tribes; the Akkadians (Latins called them Quadians); the Kassites (or Cossaei); and the Almani (or Halmani, Allemani was the Latin name).  Almani or Almain were historical terms for Germans living in southern Germany.  Without question, these Assyrian Germans assimilated with the previously established tribes of Askaeni (descendants of Gomer) and adopted their Indo-European language, becoming one people. http://www.soundchristian.com/man/
