I wonder whether Mr Howe had the finances to bring out the "Staff Workers" from the UK to South Africa. I suspect he recruited them locally from various religion-affiliated instances.
Teenagers could very well have been used to help in distributing comforts to soldiers : it looks like a young boy holding on to the tent-pole. The 4 ladies receiving a QSA were all "Miss".
I have another QSA to the unit : Mr H J Blevin. I found a reference that Mr H J Blevin from Witbank was appointed Asst District Commissioner , Middelburg , by the Transvaal Scout Council in 1923. Blevin is an unusual surname : it could imply another "local" helping Mr Howe.
I bought the QSA to K Taylor, Servant from Norman Collett in 1982 and for some 20 years I was under the impression that "he" was an officer's servant.
However, when I got a copy of Sheila Gray's publication "The South African War 1899 - 1902 : Service Records of British and Colonial Women" it transpired that Kate Taylor was a Servant to Nursing Sisters!!
However, with a name like that I wonder whether even Rory's formidable digging capabilities will unearth any further info on the lady!! The QSA roll page was signed at Bloemfontein, and that may perhaps indicate that she was a local Free State resident.
