I believe that this may be the death record for Mary "Russel" Grenier:
Mary Grenier Michigan Deaths and Burials, 1800-1995
birth 1849 —New York death 11 Dec 1920 —Cheboygan, Cheboygan, Michigan parents: John Rushlo, Unknown

Again, there is a difference in the birth year. Often, the person reporting the information was unsure.
Given herein is the name RUSHLO for her father.This could be Rousselot or ROCHELEAU. I do not think that it is ROUSSELOT as most Canadian Fr of this name have not survived to this period. The progenitor for the ROUSSELOT all died not leaving male heirs. So, it is more likely that the name may be ROCHELEAU. Most ROUSSELOT found in the US today are of German extraction.
