Hi Brian,
I believe this burial record image on FamilySearch is Esther's burial record (S3 on right page):
"Québec, registres paroissiaux catholiques, 1621-1979," database with images, FamilySearch (image : 14 August 2020), Knowlton > Saint-Edouard-de-Knowlton > Baptêmes, mariages, sépultures 1880-1899 > image 222 of 337; Archives Nationales du Quebec (National Archives of Quebec), Montreal.
Buried 6 May 1893, Esther Pratte, wife of deceased Pierre Touchette, died 3 May 1893, age 89 years.
You and I appear to be 6th cousins once removed through Esther's paternal grandparents Charles Clement Prat and Marie Charlotte Bourbeau.
