If anyone has access to death records for Ste-Marie-de-Monnoir, could they check the following:

I have verified that Joseph Hazen died in Ste-Marie-de-Monnoir on December 26,1835 and was buried on January 7, 1836. However, I have now been told that Betsy or Betty (Whitney) Davis Hazen also died in 1836 and the children were orphaned. Since I can no record of an epidemic at this time, it would be appreciated if someone could locate a death date for Betsy.
Thank you .... Brian hazen
