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 first told us that the Berubes are bearers of a mutation (also named a SNP) identified as R-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 are deepening in Le Monde Berrubey. The most recent findings concern our belonging to a branch of S-15627 that is characterized by SNP JFS0091, to which are also attached people by the name of Tatum. From there comes a more recent branch, the one of SNP JFS0367, that we share with a Carlgren (Kärlgren) from Sweden.
