Ancient Roman historian tacitus wrote that iberians have blonde and red hair

Cornelius also, the author of the Annals, says that in the farthest part of Britain the night gets brighter and is very short. He also says that the island abounds in metals, is well supplied with grass and is more productive in all those things which feed beasts rather than men. Moreover many large rivers flow through it, and the tides are borne back into them, rolling along precious stones and pearls. The Silures have swarthy features and are usually born with curly black hair, but the inhabitants of Caledonia have reddish hair and large loose-jointed bodies. They are like the Gauls or the Spaniards, according as they are opposite either nation.
