Hi
Don't know if this is too late, but my great grandfather fought with the Duke of Cornwall Light Infantry in the 2nd Boer War.
I found his service record at Kew, when I was there for other reasons. But I tried the link on the find my past website, and it didn't find him!
You may have found your man!, but if not maybe give the "British Army Service Records 1760-1915" on the find my past website, because my g grandfather does appear on that list.
Kind Regards
Trippy
