This is the record I have, from Vital Statistics in Newfoundland, regarding Modeste (Bernard) Halbot:
May 2 1906, in St. George's of Old Age, Modeste Halbot, female, age 73, Roman Catholid, born in Cape Breton, and buried in Sandy Point.
In your search, please note the death record of Appoline Bernard I mentioned as "Appoline" is equal to "Pauline" in many records, similar to "Marie/Mary, Jean/John". That record may be the death record of Modeste's mother, Pauline Bernard.
Proof is always best as MyHeritage has several if not thousands of errors: my personal experience had my great-grandfather with three wives, and while one was his wife, the other were news to us because two of them apparently married him at the same time as his wife was living and having children with him! In fact, he had only one wife and one of the other listed was married to his brother, and the third died 10 years before their apparent marriage date.
Best of luck in your search. There are Acadian families named Bernard as well as some First Nations families.
