Using BMS2000, I cannot find a marriage record in Quebec for Toussaint Raymond and Sophronie Neveu (Nepveu).
However I did find one for : Francois Raymond dit Toulouse to a Sophronie Raymond on 12 Aug 1867 at St-Jean-sur-Richelieu (St-Jean-L'evangeliste).
IT is possible that in the transcription for the purpose of BMS2000 database that Sophronie's surname was incorrectly inserted as Raymond vs Neveu (Nepveu).One would have to check the actual marriage record using Drouin church records for Quebec on Ancestry.com.I do not have a membership but I can access it at my Gen. Society.
If you Jules (Julius) was born in 1864, the above couple cannot be the right one.
BMS2000 does not list descendats of Francois and Sophronie who would have been married in Quebec.
