I guess Galicia is a region quite unknown in Europe. Located in the northwest of the Iberian peninsula shared culture with northern Portugal.
Most people will be surprised by the genetic data. As for the Y-DNA, atlantic component (R1b) is the most abundant 58%, but does not reach the level of 70% or 80% of the Basque Country and Wales. the Galician population is genetically more diverse than at first sight appears.
