Over 90,000 people volunteered for the British Red Cross in Britain and overseas during the war. Search for your family’s personnel records, and discover what Red Cross volunteers were doing in your local area 100 years ago.
I find that if you pop 'Australia' into the location search box, it will bring up volunteers who gave an Australian bank as their address, or sometimes Australia in their address. You can try other local names. For instance, I found the following British Red Cross volunteer by putting 'Moonee Ponds' in the location:
Mrs Ivy Wilson Jenkins, nee Graham, is in the database, giving 2 Normanby St, Moonee Ponds, Australia as her address. Ivy served from 01/09/1916 to 01/06/1918 as a VAD, engaged in Ward work, medical Surgical work, for twenty pounds per annum. She served at the following locations: Exeter War Hospitals Sept 1- 1916 - Aug 30; 1917 1st Southern General Hs Nov.5.1917 - June 7. 1918 Birmingham.
There are no Jenkins' at the Normanby St address in the Empire Called database, but further research may reveal more about Ivy Jenkins at a later date.
