Germany
Middle English: from Old French germain, from Latin germanus ‘genuine, of the same parents’.
wiktionary
From Middle English Germanie, from Old English Germania, from Latin Germānia(“land of the Germans”), from Germānī, a people living around and east of the Rhine first attested in the 1st century B.C.E. works of Julius Caesar and of uncertain etymology. The exonym was said by Strabo to derive from germānus(“close kin; genuine”), making it cognate with germane and german, but this seems unsupported. Attempts to derive it from Germanic or Celtic roots since the 18th century [1] are all problematic, [2] although it is perhaps cognate with the Old Irish gair(“neighbour”). [3] Doublet of Germania.
etymonline
Germany (n.)
c. 1300, "region of continental Europe inhabited by Germanic peoples," in a broad sense, from Latin Germania, a Roman designation (see German (n.)). In Middle English the place also was called Almaine (early 14c.), later Almany (16c.-17c.); see Alemanni. Middle English writers, following Latin, sometimes wrote of two Germanies, distinguishing the Alps and the region below the Danube from the region above it.
