Re: Roch Manitouabeouich and daughter Marie
I think you are correct about the name implying a divine connection of some sort and I enjoyed your post. I have read that Roch's name was one signifying spiritual power and that it may have connoted a "shamanic" role. Elsewhere I have seen speculation that he was a "chief" but I am not now inclined to believe that.My understanding is that the name was not bestowed by missionaries upon the family.I have no information that Roch converted to the Catholic faith--although it appears well documented that Marie did.
I believe the surprising (surprising in that Marie's was the first registered marriage between a Frenchman and aboriginal in Canada) dearth of information about the family may arise from the fact that many of the descendants from the union may have sought to distance themselves from it for social purposes. My mother reported having an aunt who hired a genealogist and then destroyed the record for which she paid him after receiving it. Things have changed considerably in the last few decades.
By the way, I was born in New Hampshire; my grandparents in Quebec Province (Roy, Boucher).
Best regards, Craig
