There is genetic research which connects the 'Basques' and the indigenious Briton's/Welsh/Scots and Irish. But the connection is still being debated.

It would seem the debated connection has reached one conclusion. That conclusion is, the native Britons and the Basques are the original settlers or aboriginal inhabitants of Europe.

Britain and the Islands are not Celtic or Franco-Germanic (Anglo-Saxon), but Indigenous British/Scots/Welsh/Irish who adopted absorbed immigrant culture.
