Thanks, Stella. Bert is the husband of Hattie (Dunham) Dolson.
As for the "unnamed Dolson", I see that comes up in the OFCA, so I checked with FindAGrave, Billion Graves and the names at Genweb, but no luck there. : (
A few years ago I had made an inquiry about the Shelburne Cemetery to see if the child was buried with his mother, Sarah McLarey(sic) Dolson. I believe it was Sheila Davidson who responded and said there was no record of a child in that grave. Apparently if a mother and baby died together, they put the baby in with the mother for burial.
Now my curiosity has been aroused as to the unnamed Dolson. I was about to say I shall have to do some more digging, but that didn't seem appropriate. : )
