My fertile streak isn't over yet. Here is a brand new map of haplogroup R1b-S21, associated with the migration of Germanic peoples, especially tribes originating around the modern Netherlands, North-West Germany, Denmark and Norway, such as the Anglo-Saxons, the Franks, the Lombards, as well as the Danish and Norwegian Vikings.

Note the hotspots around the Belgian provinces of Hainaut and Luxembourg, as well as in the Grand Duchy of Luxembourg, obviously of Frankish origin. Another hotspot is lower Austria, probably of Lombardic origin.

Lower frequency around the Harz mountains in Germany, due to the higher percentage of I2b.
