Regarding Clark, RFA, just now I had a trawl through my invaluable RA CD. I found him as "6325 Dvr. Clark W of No.2 Local Ammunition Column" on page 231 of WO100/144. Marginal note says "Killed by lightning, 22.11.00". The roll page on which he appears is headed "Specially Enlisted Artificers, RA" and his clasps awarded were Cape Colony, Orange Free State and Transvaal.
