Help with French handwriting

If anyone has access to Quebec vital records online through
ancestry.com
(I get it free through the public libraries here) could you help me
with a bit
of French?

Otherwise go to the 1836 records for St. Antoine de Tilly, page 5.5,
the marriage
record for Antoine Roy and Marie Constance.
I can see that she is a minor, but what does it say after that? It
looks like
"something" was "proven" by a certificate from Melchiore Potvin, the
cure'
of...where?
Thanks to anyone who looks!
