He asked the supplementary questions, that should be useful provided it was him.
But looking at the 1930 census for Julia, William, John, and Bernard Morrison, it shows Julia to be from Romania and William from Germany. As far as anyone in my family knows, they are Irish (Although perhaps my father's memories could be muddled, as I believe his mother was Irish and Welsh). Nobody remembers a Bernard Morrison either. Perhaps he died during WW2 and therefore the father (John P) never mentioned him to his children?
