The R1b haplotype is believed to be a Marker for men that descend of a few men that wintered in a "Refuge" ( a warmer area ) in Iberia ( Spain, The Iberian Peninsula ) during the last Ice Age. When the Glaciers melted they migrated to the North, France, the British Isles, etc ...
Rib is most concentrated in those areas along Europe's western coast. The populations having the highest percentage of the R1b haplotype are found amongst the Basques; those countries inhabited by a Celtic population, such as Ireland, Wales and Scotland.
Y-DNA Haplogroup R1b is the most frequently occurring Y-chromosome haplogroup in Western Europe.
More specifically, its frequency is highest in Atlantic Europe and, due to European emigration, in North America, South America, and Australia. In southern England, the frequency of R1b is about 70%, and in parts of north and western England, northern Spain, Portugal, France, Wales, Scotland, and Ireland the frequency of R1b is greater than 90%. R1b is the most frequent haplogroup in Germany and it is also found among Italians, particularly in northern Italy.
R1b is also present at lower frequencies throughout Eastern Europe, Anatolia and parts of North Africa and appears in an isolated pocket of Sub-Saharan Africa
