H18b

[Astur_Cantabri]

I inherited this haplogroup from a familial line that traces back to the Azores (Faial island). The genetic substructure identified in the local population is uniquely characterized by significant levels NW European (Anglo-Dutch) admixture. [They are the only Iberian population cohort belonging to an offshore autonomous region that is characterized by lower levels of African and Levantine admixture and higher levels of NW European introgression than those observed in the mainland Iberian host population.]

The modern distribution of H18b includes France, England, the Netherlands, Portugal and Germany. The only aDNA samples found with this haplogroup thus far come from a Lombard grave site in Central Europe.

Feel free to share any additional information you may have relating to this haplogroup.

Not related to this specific haplogroup, but anyway: there' an interesting fact: the haplogroup R1B-U106 of NW European origin (Germanic) is overrepresented in the Azores, compared to other Iberian populations. According to the paper which contained that information:

"There is a strong bias towards the Azores and Canaries (36% of families for 5% of the population), which may indicate influence by a non-Iberian population"

Just a correction though: the percentage of native european autosomal DNA among Iberians is between 90% and 100% (the rest is residual), and around 50% (from Bell Beakers and Iron age Celts) of that ancestry is NW European already, being the remaining 40% Iberian Neolithic Farmers and European Hunter-Gatherers..
