I've just returned from a vacation w/ my wife from Churubusco, NY. We took her grandmother (Rose Lafave) who is the daughter of Esther Daigneault and Samuel Lafave. Esther was the daughter of Paul Daigneault and Celeste Tavernier.
So I've married a great-great-granddaughter of Paul and Celeste.
Any information you have concerning antecendants and descendants would be appreciated. Hopefully you've gathered more info since your original post.
I've got a photo of Paul and Celestes gravestone, marked "Paul" and "Celester" "Denno", hand made of concrete into a cross.
