Raymond Mark Barrell, one of the sons of Abraham and Sarah, served in the first world war. He fought at Gallipoli. After serving in many of the theatres of war overseas, he was chosen (as an arms expert) to be part of the Dunsterforce (also known as the Hush Hush Army) commanded by General Dunster in early 1918. This force was made up from soldiers from the Dominion who were all experts in their particular fields. Read about it by looking up 'Dunsterforce' on Google.
