I am the great-granddaughter of Alexina Dufour, her children being Reno Dufour and Rina Dufour (married to Robert L. Pelletier). Rina (now deceased) was my biological maternal grandmother. If we are both barking up the same tree, so to speak, and you are still seeking info (judging based upon the date of your post), I have a pretty extensive hand drawn graphic of the family tree. Feel free to contact me via email, as I'd love to exchange info.
