The British are very Germanic they are mostly Anglo Saxon a Germanic people from Europe. People from Ireland,Scottlan,and Wales can sometimes be darker not all Irishmen are red haired and blue eyed some are actually dark haired and dark eyed so the British do have a slightly more "Germanic" character. Galician,Spanish,Portugues etc. all come from Latin an Indo-European language most European languages derive from this for example mother/madre/mutter/mae etc etc. this is the word for mother in English, German, Spanish and Portugues. father/padre/vatar etc. all are indo-European languages. Galician is derived from latin brought into Spain by the Romans no? But of course even though it developed right beside Castillian of course of course their is no realtionship at all between the languages of course it is all for political reasons LOL. The only non indo-European language on the Iberian peninsula is the Basque language. I believe Celts wre mainly a mix of indo-European and old-Europeans which is why the Scottish and Irish "Celts" are basically blood brothers to the Basque on the Y chromosones. I don't think their is a "Celt" race.
