The headstone for Euphemia Rowan clearly says MIDWIFE and that word has the largest size engraving on the headstone... Check Find-a-Grave

(If link doesn't work, go to Find-a-Grave, click on "Search for a cemetery" from "Find Grave" on the right side.
Then for cemetery name type " Melville Presbyterian ", change the country to Canada, and click "Search". As I write, it is the only cemetery that appears.
To search family names, type " Rowan " under last name and click enter. Choose Euphemia and then click on the picture to see a larger version of the headstone.)
