Welsh

There is no such thing as "Welsh". The meaning of the word, in German Saxon English is, Foreigner, Stranger.
There is no other people, race, ethnic group, or nation in the world named "Foreigners", and in this case - "foreigners" living throughout history in their own homeland!
A more appropriate name for the "Welsh" should be Romano-British (unfortunately awkwardly long) as descendants of the former Roman Province which lasted 500 years (e.g 1450-1950).
The Britons learned and spoke Latin to communicate with the Roman authorities. Romans married British women partners on retirement from the Army, employed British workers in construction and agriculture. Britons were recruited into the Roman Army.
There was sufficient cultural integration for so much of the Welsh language to include very many Latin words, as English contains German words.

The majority of the English were Saxons (Essex, Wessex, Sussex), with a minority of Angles (E Anglia). The covering name English was perhaps adopted by the Saxon invaders because the name Saxon (Scottish - Sassenachs, Welsh - Saeson) was hated by the Britons.
