Clarence Mobley - Clarence Mobley is not a child of Doris and Richard

This child was entered on our family tree many years ago by a cousin who has incorrect facts. Doris and Richard had three children, Shirley, Joyce and Raymond. Raymond died at the age of twelve months from a hole in the heart. Someone remembered a child during the war years that disappeared and decided he must have been adopted out. He died and my grandparents where devastated as where my mother and aunt who both remember him clearly and the resulting despair of my grandfather in particular. My Aunt Shirl contacted me in 2000 and asked me to look into this rumour which I did. I have grandma's NSW death certificate which also includes only three births. Doris only had three children. There was no Clarence and no Arthur (Raymonds name was Raymond Arthur).
