A Mills man and a Fortune man out of the Appalachian region of the United States had tested positive for the C-P39 Y DNA SNP. Subsequent Big Y DNA test results have yielded that both men belong to the same C-Z38940+ subclade of haplogroup C-P39, offering new possibilities for a deep ancestry connection among the two families.

Y chromosome DNA is only held by males - so this Native ancestry traces only through paternal lines. This map is showing a greater picture of this Native Y DNA haplogroup, as transmitted from father to father to father, than was previously assessed. From limited data we had from earlier DNA studies, referencing a small group of men, this Y DNA haplogroup was found to have an "Athabascan" tribal connection.
The C-P39 Y DNA study (that has been ongoing since approximately 2008) included men belonging to this haplogroup who trace earliest male ancestor locations to all regions out of North America including the Pacific Northwest, the American Southwest, the Appalachian region, Louisiana and Texas, and Eastern, Midwestern and Western Canada. Note: the map reflects the geographic locations of earliest male ancestors of study participants and not the regions where men participating in the project live today. The updated C-P39 haplogroup map also includes the "diaspora" location of descendants of Germain Doucet b. 1641 because a Doucet line -- the male descendants of son Laurent - was essentially split off from others when the Acadians, including those of Native ancestry, were deported from Nova Scotia in 1755 by the British.
Now, based on advanced Y DNA testing of a much larger population of men (whose ancestries trace to all regions of North America as shown on the map), this rare C-P39 Y DNA haplogroup has a broader distribution, geographically. As more results come into the project -- as more men participate in the advanced Y DNA studies - this map will continue to be updated.
