We found a descendent of Abraham Dugas to do a DNA test. All men who descend from Abraham Dugas of Acadia will carry the same DNA genetic signature.
The DNA test participant was Jean Jacques Dugas of Montreal and the results place Dugas men into Haplogroup J2. This is the same Haplogroup as the Dugas dit Labreche family but the DNA also shows the 2 ancestors were not related. J2 is very rare among French Canadians, found in only 5%. It is a haplogroup that is most frequent today in the Middle East and to a lesser degree in the Mediterranean. It is very common among Jewish people today, actually the most frequent haplogroup at about 30%. It was for this reasoning that we had the testing done. First, the surname Duga is common among eastern european Jews. One such Duga even has theorized his family line escaped the Spanish inquisition. Second, his given name was Abraham, which is a common Jewish given name. Third, his mother's name seems to have been Cassonne or Carsonne but neither name seems to exist in records. However, the surname Carcassonne does and it was often a Jewish surname in the south of France during those times. It is found very frequently in the Jewish records from Avignon, right next door to where we find the highest frequency of Dugas' today in France, Gard. The Dugas men have very few close genetic links, the closest being a man from Hama, Syria. Both the Dugas and Dugas Labreche families carry a genetic signature quite different from that of their other French Canadian peers.
This DNA result does not prove Abraham Dugas or Jean Ducas/Dugas dit Labreche were of Jewish ancestry, but it is very strongly supportive data for any theory that he was.
