Hiya,
Constance Harriett Groom did not serve in the Boer War as a nurse. You can see the database here:
https://boerwarnurses.com/boer-war-nurses-database/. The nurses working for the military in South Africa were trained nurses. Some were in the military, some were already in South Africa and offered their services, and some travelled to South Africa and then offered their services. The medal rolls for nurses are extensive and well documented.
cheers
Keiron
