Hello Hugh.
You could find some info in this book
At His Side. The Story Of The American Red Cross Overseas In World War II
by George Korson
It's not difficult finding the book but it's also avaible on line

In the same digital library you can see also a film with the same name distributed by the War Activities Committee in 1944

Was she assigned to ETO? I have a list of the A.R.C. workers in this theatre assigned to the Clubmobile DIvision (aka "doughnut dollies").
All the best
Fano
