Haplogroup R1b (Atlantic Modal Haplotype)
The Atlantic Modal Haplotype is the most common variation of R1b. It is defined by the
six basic marker values below.

This and related R1b haplotypes originated in Europe during the Paleolithic. During the Ice Age,
the carriers of R1b wintered in the Pyrenees. When the Ice Age ended, these carriers radiated across
Western Europe. They became the pre-Roman population of Spain, France, the British Isles, and large
portions of the Rhineland, Belgium, The Netherlands, Switzerland and Northern Italy.
Although the Celtic language itself has roots in Asia, the indigenous people of Western Europe
became its primary speakers. They comprised the largest proportion of those people we know from history
as "Celtic", and remain so today. Traditional areas of Celtic settlement are Ireland, Wales, Scotland,
Cornwall, Brittany, and Galicia in Northern Spain. Celtic culture is epitomized archaeologically by the La Tene
settlement, which existed near Lake Neuchatel in Switzerland during the Iron Age.
The Paleolithic population of Europe also became one of the earliest components of the Spanish,
Italian and German peoples, and were among the first speakers of the the Romance languages and the
Teutonic languages, even though the Indo-European source of these languages, too, lay elsewhere.
The Basques, who are perhaps the purest "Paleolithic" population in Europe, do not speak a
Celtic language and are not Celts, even though they are ancestrally related to those who are.
R1b does not mean "Celtic". And, even though R1b is found everywhere in Western Europe,
no country in Western Europe is entirely R1b, or has been so for a very long time.

This appears to be far more common among Basques than any other group. Two other
frequencies in the top ten occur in Iberia or Latin America, three occur among white Americans in
Indiana, Texas and Pennsylvania (all of which have a history of British or Scots-Irish settlement),
and one each occurs in Northern Italy and the Rhineland.
This haplotype most likely entered Britain with the prehistoric Iberians, and proliferated
among the Picts, Welsh and the Cruithne of Ireland.
There are hits in Russia and the Ukraine, which are unusual for an R1b haplotype, but
which may be attributed to the spread of Celtic culture to Poland and beyond.
(An additional source of Iberian R1b in Eastern Europe may be the Sephardic diaspora
of The Late Middle Ages.)

Atlantic Modal Haplotype #18
This haplotype is not common, but it exhibits its highest frequencies in the Rhineland
and Iberia. It is most likely of Iberian or Celtic origin.

Atlantic Modal Haplotype #20
This haplotype is too common to be restricted to one place of origin. Of the top ten
frequencies, seven are among Basques, Spaniards or Hispanic Americans. This definitely
suggests that a person of British origin with this haplotype is descended from the Iberians
who came to Britain after the last Ice Age.
However, of the top ten European frequencies, two fall in Denmark and Sweden,
and one falls in Paris, France. The Cajuns, who are of predominantly French-Canadian
descent, rank sixth. Our hunch is that some of those with this haplotype may be of
Scandinavian origin - or, at the very least, descended from the Normans. The
Normans were not only of Viking stock - there were many Bretons among them as
well, and it is important to consider that the Basque country and the Pyrenees
are not that far from Brittany or adjacent French regions.
This haplotype has many hits in other locales, including The Netherlands,
Germany and Scandinavia.
An Iberian or "Celtic" origin is, again, most likely for most Britons or
Anglo-Americans with this haplotype, but some of these Britons undoubtedly
had other origins.

This haplotype exhibits its highest frequencies in Sweden, Ireland, among Americans of
possibly British or Irish descent, and in areas which have a Celtic history, but which were
also influenced by Normans, such as Zaragoza and Belgium. Both Paris and London
also appear in this table, but not at such elevated frequencies.
The match pattern for this haplotype is not unlike that for 14-14-30-24-11-13-13-11-14,
which is only step away on DYS389ii. But while the other haplotype suggests a Viking
or Norman origin only as a secondary possibility, this haplotype suggests it more
strongly.
There is also the possibility that both of these haplotypes may be signatures of
the Hiberno-Norse or "Gall-Gaedhil". These were Irish Gaels who joined Norse
society, either as slaves, warriors or camp followers. The Hiberno-Norse
accompanied the Norse to Iceland, Cumbria, and the Isle of Man - and perhaps
even to Normandy or back to Norway itself. This would account for how a
seemingly Celtic-Iberian pair of haplotypes could have made its way into a
Scandinavian context.
