I am fairly confident I am apart of the line you are talking about. My g grandfather is Alcide. His family came to the United States, they had another son in VT, where they lived. My g grandfather passed about a decade ago, one of his sons has done extensive research tracing this line back to about 1633, I am working on getting my hands on it now. I would be more than happy to share this information with you once I get it from him.
