Relatives in New Zealand or Australia

Hello my name is Roy Rennan and I am seated in Norway. My grandfathers name was Horace Rudge born 1897 in London. His parents where George Rudge b. 1860 and Florence Wilson b. 1867. My grandfather had 7 siblings and I think at least two a brother and a sister emigrated to New Zealand or Australia. His siblings where: Florence Rudge b. 1887 and could have been his sister that left England, George Rudge b. 1889 lived in London, Albert Rudge b. 1890, lived in Australia?, Hilda Rudge b. 1893 went to Canada and married Loveridge (see correction), John Victor Rudge b. 1895, Alice May Rudge b. 1898 and Leonard Baden Rudge b. 1900. My mother wrote to a cousin in Australia named Anita Oyers, last known adress: c/o Belmont Auto Motel Gt. Eastern Highway Belmont Perth 6104 W. Australia. If any one has any information about this above I shall be very happy. Thank you Roy [:)] Ps I have some pictures but dont know how to insert them in this topic. Correction to topic. It was Florence Esther Rudge who went to Canada and she married Charles Sewell.
