In accordance with Family tree, the R1b Z-278 is also found in the south west of France, as well in the United Kingdom, including Scotland, and some presence in Ireland, Italy and Puerto Rico. It is also found among Americans descended from the first settlers of Massachusetts and Virginia.[6]References1. ^{{Citation |last= |first= |year= |title=Y-DNA Haplogroup R and its Subclades - 2018|publisher=International Society of Genetic Genealogy|publication-place= |page=|url=https://isogg.org/tree/ISOGG_HapgrpR.html|accessdate= }} 2. ^{{Citation |last= |first= |year= |title=Discovery of Western European R1b1a2 Y Chromosome Variants in 1000 Genomes Project Data:|publisher=PLOS One|publication-place= |page= |url=https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0041634|accessdate= }} 3. ^{{Citation |last= |first= |year= |title=Where does the haplogroup R-Z278 originate?|publisher=Michael Ruby|publication-place= |page= |url=https://www.quora.com/Where-does-the-haplogroup-R-Z278-originate|accessdate= }} 4. ^{{Citation |last= |first= |year= |title=Haplogroup R1b (Y-DNA)|publisher=Eupedia|publication-place= |page= |url=https://www.eupedia.com/europe/Haplogroup_R1b_Y-DNA.shtml|accessdate= }} 5. ^{{Citation |last= |first= |year= |title=En busca del padre de todos los vascos:|publisher=El Confidencial|publication-place= |page= |url=https://www.elconfidencial.com/espana/pais-vasco/2017-09-27/origen-vascos-descienden-antepasado_1450158/|accessdate= }} 6. ^{{Citation |last= |first= |year= |title=R1b-DF27 and Subclades Project|publisher=Family Tree|publication-place= |page= |url=https://www.familytreedna.com/public/R1b-DF27?iframe=yresults|accessdate= }} External links
