Are you still looking after all this time? According to Robert Chenard's "Marriage Record of St. Francis de Sales", Pierre Paquet (son of Eustache Paquet & Sophie Genessee) married 4 Aug 1889 Louise Belanger (dau. Octave Belanger & Regina "Jane" Ouelette). I think you ought to browse Bob Chenard's website "the French Connection").
Incidentally, Vital Records of Fairfield, Maine adds another child: Joseph Saloman Paquet, born 4 Aug 1892.
