Marie Mathilde Goulet was born 29 Mar and baped 30 Mar 1851, St-Thomas (Joliette), PQ, CN.
I found 16 bap records, 3 burial records, and 12 marriage records for children of Olivier Goulet and Marie-Odile Coutu.
I found no marriage record for Mathilde, perhaps she became a nun?
These parishes has various records for this line: The bulk were in Ste-Élisabeth (Seigneurie Dautray) and St-Thomas (Joliette), a few other's in these parishes: St-Félix-de-Valois, Berthierville (Berthier-en-Haut), St-Charles-Borromée-de-l'Industrie (Cathédrale de Joliette), and St-Calixte-de-Somerset (Plessisville).
I used (fee based) /
www.genealogiequebec.com to rough out the line.
A (free) cleaner/clearer copy of the parish records can sometimes be found on familysearch.org:
