I have some Marriage records, I'm searching for more records right now. The thing is this. Some Dupuis are Dupuy and some are Dupuy Montpellier or dit Montpellier. so I have a family/marriage record for Joseph and he's Dupuy Montpellier and a death record for his daughter Marie and she's MarieMontpellier, in the written part she's Montpellier dit Dupuis, on Find a Grave she's Dupris dit Montpellier but on the family/marriage record she's Marie Dupuy Montpellier. Well, I'll assume that since they only show the father's surname.
