Thank you Kris!

On the basis of the information you have provided, I have just spent some time searching the NAA site for any mention of any of the sons of Thomas Herbert Jones that you have listed for me.
Sadly I have so far found that Spencer Roy was killed in action in France. His army records make for sobering reading. I have just finished reading Ben Elton's book, "The First Casualty" and in it Elton so vividly describes a horrifying experience to one of the lead characters that is identical to that of Spencer. Terrifying.
Apparently another brother was also killed, according to a letter to the army from his mother, F. Jones, but I have yet to find which one.
Thanks again for your help Kris. Much appreciated.
