Hello, sorry for late reply, yes indeed, there are a number of memorials, I would think they are on the national memorial in Cardiff, in the particular case of Deverill and Jones, they will also be on the Royal Welsh Fusiliers memorial in Wrexham, the regiment had it's Depot there, at Hightown Barracks, built before the Anglo Boer War, I have always liked the RWF and considered them to be, very much a local regiment
The memorial in Holy Trinity is particularly ornate and ranks as one of the best and most pleasing that I have ever encountered to just two men.
They are both an awful long way from home at Kimberley's West End and Cape Town's Maitland respectively.
