Dugas Family Genealogy Forum
The DNA result on the Y chromosome follows direct paternal descent so only direct male descendents of Abraham Dugas would carry this Y chromosome signature. The same goes for mtDNA which follows a direct maternal lineage. The Y-DNA J2 result for the Dugas men has now been found in 2 direct descendents, one from Canada and one from the southern US which pretty much confirms that this was the genetic signature of Abraham Dugas. The same goes for the descendents of Jean Ducas-Dugas dit Labreche. Both ancestors were unrelated but carried a Y chromosome signature indicating haplogroup J2. This signature is found in about 5% of French Canadian men. About 80-85% are in haplogroup R1b or I which are indicative of Western and Northern European deep ancestry.
