I checked the transcription today for Lakeview and it doesn't appear that the Archibald Cumming buried in this cemetery is the one you are looking for. Here is the information from the transcript:

Archibald Cumming
Dec.29, 1894-July 31, 1967
and on the same stone:
Jean Speirs
Jan. 31, 1895-July 11, 1967

There is a Mary Cumming buried in another section of the cemetery (died 1880, aged 80 years) but she is on a stone with several persons with the surname of Monro. They appear - just a guess - to be an adult son, daughter-in-law and several of Mary's grandchildren.

The only others with the surname Cumming in the transcript are James S. Cumming and wife Ann M.

I copied down the information for the Munro burials and also for James and wife Ann should you need it.
