The hard Teutonic-Celtic split of peoples dating from the Anglo-Danish invasions is a hangover from the years of English subjugation over those three nations. It was convenient for the English and is now convenient for "Celts" to have this exist as a widely-held belief.
What? Over 50% of English and Lowland Scottish males belong to Germanic paternal lineages (I1a, I2a2a-Z161, R1a-L664, R1a-Z284, R1b-S21/U106). The usual for England is 55%-65%. So sorry there is no hangover.
