I spoke with a local Basque, neighbors to the Pasiegos, and he explained to me what they know from those 20-40% dot people. The singular and heavy presence of Pasiegos in the northern mountains of Iberia, and their spread among Cantabrians and some Basque territory, is attested since the XII century or earlier. Their origin seem to be owed to Royal grants on their valleys (and those of other peasant local folks) to have free range on all the communal pastures of others, and to be free of any taxation for it from the nearby nobility or Abbots, what made them hated and subject to all sort of mistrust from sedentary farmers, and to isolate themselves to shield their rights and cast abuses off. They couldn't tell me or didn't know, where the Pasiegos came from before that, or the reasons for their grants of such privileges. No later Gypsies or others foreigners were ever known to have such freedoms or territory rights, given among and above Christians, except those with similar royal grants around those centuries, given to the so called "Francos" to settle along the Compostela road valleys, fords or towns. But those were known from where they arrived, with their foreign family names and own languages, been called to do so all the way from Aquitaine, Champagne and Lower Saxony. Did Kings trade settlers with the Emperors of Central Europe, the Poles or Baltic Lithuanians in those "population booming" days before The Plague? Could Iberian families have ended up too in the other far away Christian new marches of Prussia, called along the French by the Knights of those places to settle "new territory"? How much medieval colonization was done over as vast distances as the Crusaders did?
