HAPLOGROUP INFORMATION
* E-L117 was previously known as E-M35 or E-M35.1, and has also been referred to in the literature as E1b1b1. Previously, it had been assumed that haplogroup E1b1b1 (E-M35) arose in East Africa and the haplogroup was often incorrectly described as African, leaving a misimpression regarding the origin and complex history of this haplogroup.
* The R-M222 branch of the Y-DNA tree is defined by a Single Nucleotide Polymorphism (SNP) called M222. This diagnostic marker is associated with many individuals whose roots lie in the counties of Northwest Ireland, Ulster and Lowland Scotland. https://www.familytreedna.com/groups/r-1b-1c-7/about/background
* R-M269, also known as R1b1a1a2, is a sub-clade of human Y-chromosome haplogroup R1b. It is of particular interest for the genetic history of Western Europe. It is defined by the presence of SNP marker M269. R-M269 has been the subject of intensive research; it was previously also known as R1b1a2 (2003 to 2005), R1b1c (2005 to 2008), and R1b1b2 (2008 to 2011).
Haplogroup I
* Haplogroup I-M170 is a subgroup of haplogroup IJ, which itself is a derivative of the haplogroup IJK. Subclades can be found in most present-day European populations, with peaks in some Northern European and South East European countries. This haplogroup reaches its maximum frequency in the Western Balkans (with the highest concentration in present-day Herzegovina).
* I1 - Subclade M253 is the primary branch of haplogroup I* (I-M170), which has been present in Europe since ancient times. The haplogroup reaches its peak frequencies in Sweden (52 percent of males in Västra Götaland County) and western Finland (more than 50 percent in Satakunta province).* I2 - Subclade M223. The age of YSTR variation for the I-M223 subclade is 13.2±2.7 kya and 12.3±3.1 kya. I-M223 has a peak in Germany and another in eastern Sweden, but also appears in Romania/Moldova, Russia, Greece, Italy and around the Black Sea. Haplogroup I2a2a has been found in over 4% of the population only in Germany, the Netherlands, Belgium, Denmark, England (excluding Cornwall), Scotland, and the southern tips of Sweden and Norway in Northwest Europe; the provinces of Normandy, Maine, Anjou, and Perche in northwestern France; the province of Provence in southeastern France; the regions of Tuscany, Umbria, and Latium in Italy; Moldavia and the area around Russia's Ryazan Oblast and Republic of Mordovia in Eastern Europe.
