If you don’t have this for McKenzie:
I can find her and husband Peter and his parents (Alexander and Mary) and her parents (James and Mary Eastman) and daughter Margaret.
OCFA, LDS and census, etc.
Mother Mary Eastman is with them in Wyoming, Ontario in the 1891 census.
I don’t see a death date for her - maybe someone on ancestry will respond.
