I have some info on Lyle W Jamieson. As you say, born in Egypt. Went to Canada, came back with the Canadian Army in 1914. Met a local Salisbury, Wilts girl and married. Did his bit in the war and divorced and re-married.
Killed in a traffic accident 1933.
I have more info coming. Shall we exchange what we have?
