This image is this posting is from 1815 marriages in St. Constant.
Alexis Robidoux married Rose Rheaume. Even those who can't read the original can see their names on the left hand side of the entry.
has indexed these records, but just the names of the couple getting married, the person who was born or died only. Many other names are mentioned, but these are not included in the index.
