William McKellar Bourke (spelt McKellor in military files) was my grandfather. I found records relating to this when I obtained a court order releasing the birth certificate of my father, William McKellar Belliss Little, when he was adopted by Simyal George Frederick Little and Hilda Mary Agnes Lodge. This document showed that WMcKB Little was born William McKellar Belliss but that his father was William McKellar Bourke.
