Maurice left for America on 26 April 1930. He set sail by himself. His other family membes had come a while before him. He left many behind in Australia who he would never see again. It's hard to imagine, but the call to America must have been over-riding of the desire to stay in Australia with the loved ones there. "Courage" is the word I would use to describe this. He was only 17 years old. Here is the link to his Identification Check with the Matson Navigation Company to sail on the ship, "Sierra."
