I hope some helpful person will see if Thomas Wallace OLSEN and Sarah Lillian TRETHOWAN had any children. They married in 1926 Melbourne, they both were born in Victoria and he died 1964 in Victoria too. I don't know when and where she died. I presume they lived in Victoria (all the time?) and if any children were born Victoria will be my first guess on a state. Thanks in advance. Helene Munch Copenhagen, Denmark
