Ben: You'll notice that there are plenty of empty spaces all around. Those are graves without grave markers. Keep that in mind. Here is the cemetery's record card for Elizabeth and Robert Sutherland.
The plot was purchased in 1886 by Mrs. E. Wilson--that is, Elizabeth Musgrave when she was still married to her first husband, Thomas Wilson.
You will notice that while the register has only two names listed, there is a notation that the plot, which contains six graves, is full. That's I believe this is where Thomas Musgrave is buried. There are four other people buried with Elizabeth and Robert. Her first husband and her father are two of them. I have no way of confirming that, but I think it is a logical assumption. I believe the burial plot was bought by Elizabeth for Thomas Wilson, who must have died in 1886. The plot was available when Thomas Musgrave died. Where else would a daughter bury her father?
Here, incidentally, is the burial permit for Elizabeth Sutherland. This was used in lieu of a death certificate to allow Elizabeth to be buried. The cause of death, in case you can't read it, is mitral insufficiency. She had heart problems.
