Maybe another out-of-use name for a country?
From Wikipedia:
Cambria is the classical name for Wales, being the Latinised form of the Welsh name Cymru (Wales). The etymology of Cymry "the Welsh", Cimbri, and Cwmry[citation needed] "Cumbria", improbably connected to the Biblical Gomer and the "Cimmerians" by 17th-century celticists, is now known to come from Old Welsh combrog "compatriot; Welshman"[1], deriving from an old Brythonic word "combroges" or Proto-Brythonic *kom-brogos[2][3], meaning "compatriots", (as a result of the struggle with the Anglo-Saxons) possibly therefore related to its sister language Breton's keñvroad, keñvroiz, "comrade", "compatriot" [4].
