CYMRY has been assigned to various guesses including COMBROGES (with the country) - employing a Classical preposition with a Celtic noun! Forget COMRADE that is merely a folk etymology. The modern consensus is that it is derived from Brittonic *Kombrogi, meaning “compatriots”. The dubious character of this, however, is the analogy of "Kom-" to Latin CUM (with). The Cimmerians and the Cimbrians are said to be ancient remnants of the tribe of GOMER. The pronunciation of Cymry , answers to this possible unattested origin being GOMER, (via the origin posed on the main page); whose descendants spread over most of Southern Europe, except for Southern Spain. However, Montgomery has NOTHING to do with Gomer! Initially, the inhabitants of South Spain were from JAVAN > ultimately IONA. ("JAVAN" is just the Anglicised spelling of the original.)
