I am sorry, but I can't help with Dupuis family as I don't have any info or pics on the Dupuis side, only Beaudry who married a Dupuis and came to Wisconsin in 1870.
I found this tree on ancestry, not sure if this is your info or someone else's research, but it appears to be a match to your dupuis/trudeau couple. http://trees.ancestry.com/tree/8553905/person/1279840083
there is a translation of the 6 July 1859 wedding record on that tree under story. This indicates parents of Joseph Raymond to be Pierre Raymond dit Duprius and the late Josephte Archambault.
