Hi Alan
I've just noticed this, which was a while ago, so you may already have this info.
The British Journal of Nursing, 1913, Aug 9th, p111

Elizabeth Mackenzie, age 27, occupation Nurse, b Glasgow
There is also a snippet in Dumfries paper when she went to Serbia, but I will have to look it out.
They were quite a bunch of women (& men). Came across your site. The aunt-in-law of my husbands aunt (still with me!!) was Agnes Atkin who went out as an orderly on the same ship as Elizabeth. I'm in the middle of putting together her history & will send it to you when finished. i'm hoping to look at SWH records in Mitchell next week.
Hope this is of some help.
