Thank you Elmarie.
As Lieutenant Arthur John Tyler he did attract the attention of Mildred Dooner who wrote:
"
Tyler - Lieut. Arthur John, West Riding Regiment., serving with Col. Plumer's Force, was killed in action north of Mafeking, March 14th, 1900. He was born in June, 1871, entered the West Riding Regt. June 1892, being promoted lieut. Sept., 1895. He was seconded in Sept., 1899, for special service in South Africa with Col. Plumer's M.I."
But this is a mere morsel of information as "Captain Arthur John Tyler 1871-1900" also attracted the attention of a Peter Millington who wrote an illustrated 7 page article about him which was published in Botswana Notes and Records, Volume 36, 2004. The link below takes you to the article which can be downloaded.
