I also am curious about this Micmac lineage and would love to see any source information which you may have. The link below is very interesting, from the Native American view of controversy.http://www.brasdorfirstnation.com/Study/Lejeune_Study.php
I have read some accountings about the early explorers and their adoption into the tribes and how they would be listed as a member upon adoption. Perhaps there is some truth to both views.
Please share any theory or proof which you may stumble across. thnx
