I dont know which is better, email or here so im posting here too my family line goes from John and Sophronia's son William, his son Roy is my Great grandfather, Roy's son Victor is my grandfather, and my father Henry. As far as obtaining a copy of the documentation, that wont be too hard, the pages are in a loose binder so it will be easy to copy. As far as the name change, we have heard that it may have been Lavoie before, but that was never confirmed. As for the Iroquois heritage, all we heard was there was some indian blood in the family, but nothing beyond that.
