Some Berubes from the lineage of Pierre and Mathurin, two sons of our ancestor Damian born in 1682 and 1688, were tested genetically. The tests revealed that the markers identified from their Y-DNA are practically identical. The tests also confirmed that these Berubes are bearers of a mutation (also named a SNP) identified as U-198, and even a more recent, R-S15627 that is found among at least half of Englishmen classified U198. This mutation appeared at least 2000 years ago in the Germans of the North Sea (Angles, Frisians, Saxons) which inhabited a territory straddling today Germany, Denmark and the Netherlands. In these countries and in England, there is between 1 to 2% of people who bear this mutation, but none have been identified until today in the francophone world, except the Berubes. The exceptional high rate of AB and B blood groups among Berubes can also be compared to what is found among Slavs. Furthermore, results recently obtained from the Big Y test help us to understand more, a subject that we will deepen in coming issues of Le Monde Berrubey.
