Thank you for all this - its great. Yes, the officer was killed. Please how do I access the KRRC Chronicle?
Try a search of this forum. Someone was asking about the KRRC Chronicle within the past week or two.
You would need to see the KRRC Chronicle for the late WW1 year in question. You could buy a copy second hand or, maybe, see it in a museum or library. However, being as you are not sure of the year in question, the best thing would be if someone who is a member of this forum would be kind enough to look and see if they recognise your officer.
I am sorry to say that I only have the KRRC Chronicles for WW2. However, it looks as if every officer killed in WW2 has an obit, complete with photo. Most of which are full page studio type pics. The KRRC was the regiment to belong to in order to be remembered, as long as you were an officer. The ORs just get their name and date of death.
